Logitech K810 Wireless Bluetooth Illuminated Multi-Device Keyboard for PC, Tablets and Smartphones, Black

There are many reviews of this keyboard, but none specifically addresses ghosting/rollover capability (such as for gaming), typing noise, or pairing to Windows 10, Windows 10 Mobile, or Amazon Fire TV -- so this is that review!ROLLOVER CAPABILITYUsing the Microsoft Applied Sciences Group webpage app (google/bing it), I first confirmed that every key works individually. Then I started adding combinations in order to find limits to the maximum amount of keypresses that can be registered at the same time. Here are some of those results:Combination ---> Result-- QWERTY ----> 7th key pressed does not register; exception = Shift, Control-- ASDF+JK ---> 7th key pressed does not register; exception = Shift, Control-- QWE+ASD ---> 7th key pressed does not register; exception = Shift, Control-- ASD+ZXC ---> 7th key pressed does not register; no exceptions-- JKL; ------> 5th key pressed does not register 100% of the time; exception: Shift, Control-- Up+Down+Left+Right --> 5th key pressed does not register 100% of the time; exception = Shift, Control-- WASD+Space --> 6th key pressed does not register 100% of the time; exception: Shift, Control, Tab-- WASD+Space+Shift+Tab+Control ---> 9th key pressed does not register-- Control+Shift+ZX ---> 5th key pressed does not register 100% of the time-- ZXC --> 4th key pressed does not register 100% of the time; no exceptions!-- (Unable to confim Alt button in conjunction with any of the above as it does not rendered on the app.)So based on the above findings, here are the obvious conclusions:1. you should be able to game on this keyboard if you use the traditional keybindings of WASD for movement, Spacebar for jumping, Shift for sprinting, TAB for team scores, etc.2. If you deviate from the traditional WASD setup then things can only get worse for you as demonstrated above -- switching to the arrow keys, for example, does not make it better but can actually make it worse.3. If some of your keys are not registering, then mapping to TAB, Shift, Control, or Alt may solve the problem.4. For unusual combinations, try the Microsoft webpage app to see what you can figure out.HIDDEN FUNCTIONSAlso via the above Microsoft website, confirmed functionality for these combinations even though they are not specifically labeled on keyboard:-- Home = FN+LeftArrow-- End = FN+RightArrow-- PageUp = FN+UpArrow-- PageDown = FN+DownArrow-- Shut Down = FN+ESC -- closes all programs and shuts down computer (Windows 10)FUNCTION BUTTONS (see picture)F1 = Bluetooth connect to device #1F2 = Bluetooth connect to device #2F3 = Bluetooth connect to device #3F4 = change appF5 = brightness downF6 = brightness upF7 = play/pauseF8 = volume muteF9 = volume downF10 = volume upF11 = HomeF12 = calculatorSOUND COMPARISONLoudest --> Quietest-- Microsoft Sidewinder X4 (membrane) -- typing is loud due to wobbly keycaps -- loudest (full N-key rollover)-- SteelSeries Apex 300 (membrane) -- typing is loud due to wobbly keycaps -- almost as loud as Sidewinder X4 (20-key rollover)-- Zalman ZM-K600S (membrane) -- slightly quieter than Sidewinder X4 with lower-pitched noise (full N-key rollover)-- Corsair Strafe (Cherry MX Silent) -- very quiet, mix of low and higher-pitched noise, like a mouse chewing through cardboard (full N-key rollover)-- Logitech K800 (scissor switches) -- very quiet, high-pitched noise, like soft footsteps on tile (limited rollover capability)-- Logitech K810 (scissor switches) -- very quiet, high-pitched noise, like soft footsteps on tile (limited rollover capability)-- Asus Cerberus (rubber dome) -- very quiet, low-pitched noise, like soft footsteps on carpet (19-key rollover)BLUETOOTH PAIRINGPaired to these 3 devices no problem:1. Windows 10 desktop computer -- via Asus bluetooth adapter USB-BT-400 -- see my review here:https://www.amazon.com/gp/product/B00DJ83070/ref=oh_aui_search_detailpage?ie=UTF8&psc=12. Microsoft Lumia 950 -- for Continuum via Microsoft Display Dock -- the trick here is to hit 'Enter' on the keyboard after typing in the 6-digit code; neither the Logitech instructions or Windows 10 Mobile pairing message specifically tell you to do that, but by pairing to Windows 10 first I discovered that it had to be done.3. Amazon Fire TV -- paired no problem as 'InputDevice' until recognized as 'Logitech K810'; 6-digit code, Enter, done. Typing registered for Amazon Music app (then Fire TV remote to 'enter'), but so far unable to register typing for the Youtube app; will update this review if find a way to do that.BACKLIGHT (see pictures)-- The backlight has 4 brightness levels (off, low, medium, high).-- The backlight is subtle -- see pictures for comparison of medium brightness to Corsair Strafe (red backlight on low) and Apple keyboard (no backlight).MISLABELED AS K811 (see picture)-- While looking closely at the keyboard I discovered that the label on the bottom actually describes the unit as K811 (the Mac version), not K810 (the Windows version). This is clearly not in agreement with the visual appearance of the top of the device (the Windows version is darker-gray, as I have), nor is it in agreement with the function of the device (which I am using with Windows 10). The only reason I mention this minor point is that it might complicate warranty transactions, if any, further down the road.SUMMARYOverall pleasant experience so far -- easy pairing, quiet typing, nice backlight. Limited rollover capability for gaming. Functionality for Amazon Fire TV varies by app -- worked with Amazon Music but not YouTube app, for example -- will update review as needed.

The keyboard works really well and I can control my laptop, phone and my tablet with 1 single keyboard. The feel of using it is great too.However after about 1/2 a year, the paint on the button start to fall off and now my space bar, A , S and E looks kinds of "different".Hence, the design is good, the quality of the product still have room for improvement.

I've purchased many Logitech keyboards and mice over the years, they work well, and the battery life is outstanding. My home workspace has changed recently, with me often using my home and work laptops (HP & Lenovo) coupled to 2 full HD monitors, and the constant hassle of using the correct keyboard and mouse with the appropriate laptop caused me to investigate Logitech's multi-device units. While reading a very recent review, someone noted that 2 devices were on a 1/2 price sale (other outlets) so I purchased a K380 keyboard in gray, and an M590 mouse. Both units worked well regarding the multi-device capability, a quantum leap IMO of functionality when you have multiple devices like desktops, laptops, and phones as I do as a programmer, though I haven't tested on my Samsung Note. The M590 mouse worked well, though it was a bit sluggish on the HP perhaps due to a Bluetooth driver, and the mouse favors right-handers, I found the left edge where a righty's thumb sits to be a bit sharp & irritating, I now hold the mouse more loosely to adapt. The K380 keyboard (reviewed on many sites as the best Bluetooth mouse currently available) worked OK, but after a few days I noticed alot of missed keystrokes, not helped by the smallish round key design, and the key labelling was indistinct and difficult to read in my lighting, and the lack of backlighting didn't help. But more importantly, I found my hands getting pained by the slightly compressed key spacing on the K380, maybe those with smaller hands (women & kids) would be OK with it, but my hands are normal size, and overall I found the keyboard literally painful and unpleasant to work with, so I returned it and after some more research got the K810 from Amazon. WOW what a difference, it is now my favorite home keyboard, replacing the K750 white solar unified (though my old Mac full-sized white wired keyboard I use at work is also very nice, fast and quiet, the best for serious work). The K810 is a beautiful keyboard, is fairly quiet, has quasi-chicklet keys with a short travel that is for me a perfect feel, and there is something about the key plastic that feels almost jewel-like, slightly concave and a real joy to type on. And the backlight turns on when needed, it doesn't always turn on just by hovering like some reviewers report, but I found that just touching my pinky slightly on the left or right edge of the keyboard depending on which hand is striking first always turns it on. My initial monitoring of battery life (Logitech & review-rated at 10 days or more) was 22 days with heavy use and moderate backlighting. All the keys are fine for size, shape and typical placement, and the lit CapsLock and [programmable] Calculator/F12 button are nice bonuses. Upper-left key is ESC, upper-right key is FORWARD-DELETE (with BACKSPACE below it), and lower-left key is CTRL (unlike my Lenovo!@#) Note a reviewer said they didn't like having to press the "FN" key to enable "normal" function key use (vs. the multi-media functions), but that is customizable with Logitech's "Setpoint" app, as are some other functions. This is just an amazing keyboard, sadly however, after about 5 weeks the "1" key started getting intermittent, failing more than half the time in my normal force typing, I started having to hit it a bit harder than the rest, with the left side of the key being particularly unresponsive, and after a while I found it to be untenable, a quick online chat with an Amazon rep and he sent me a replacement in 2 days! I hope the bad "1" key issue was an isolated event, because I do not know of a better keyboard for my situation, and it really is an outstanding device for its multi-device functionality and great hands-on feel. I rate it 6 stars, and deduct 1 for the bad key! }B^)PROS: beautiful, if Logitech makes a white one I will buy it beautiful key feel, there is nothing else like it up to 3 devices, multi-device is a must-have for me backlit keys, another must-have Lit CapsLock indicator 3-week battery life so far, great considering back-lighting small & light, but with normal key spacing standard mini-usb charging (cable supplied) tiny rubber feet to keep it anchored, but unnoticeable on your lapCONS: gamers may prefer larger arrow keys and a full numeric keypad non-replaceable lithium battery? but I read there is web info on how to replace it yourself in a year or 2 a bit pricey

For the price, I would expect a keyboard with a complete set of keys that are attached by more than a thin strip of plastic! I had read other reviews indicating problems with the keys coming up and not being able to do a simple repair by pushing them back on. Before I returned it I had problems with 3 keys either doing this or just stop working.Even with just one key doing this the typing quality is affected and after 10 days I wouldn't expect this to happen with a keyboard at any price, no less the $169.00 price point all the "Other Sellers" offer this one for. Amazon doesn't seem to carry this model any longer but when I bought it from them a month ago they had it for around $80.00. Which would have been a great price compared to the others if it was simply built better. I'm now on my third (and last) Logitech keyboard as they've all had different problems. I don't know what happened to this company but the quality of their products has really gone down hill!

I'd like to give this five stars... it's actually a really well built, useful device... except for one major problem... with the LED on, the battery only lasts a few days and there's no indication on the keyboard that the battery is low. Even with the LEDs off, it's dead in a week or two, not the 'about a year' that the Logitech site claims. I've ended up just leaving it connected to a USB port all the time to keep it powered.It might just be this specific keyboard, but a wireless keyboard with such a short battery life isn't really workable. Either bigger batteries, or removable batteries would be better.

This is a great external keyboard for my chromebook when I connect it to my monitor via HDMI cable. At first, I was not sure if it would connect or not to chromebooks because it did not state that in the description, but after purchasing it and then trying it, it works great! Actually, I am writing this review with this keyboard and my chromebook connected to my monitor.I tried turning out the lights in the room and turned the brightness all the way up, and it has good lighting in the dark. Also, when you take your hands away from the keyboard for a few seconds, it recognises it and turns the brightness down a little, and then if your hands are still not there, then it turns it off to save power. When you put your hands close again, it turns back on to full brightness. Also, if the lighting in the room is bright, the illumination does not turn on, to save more power.The keys are nice, they do not make a banging sound when you tap them, and what is nice about it, is that I got used to this keyboard in a matter of 5 minutes as I am already typing very fast.The metal cover behind the keys is nice, and it makes the keyboard look expensive.Overall, I recommend this keyboard to anyone looking for a portable keyboard.... it is a little smaller than a regular keyboard but its great for portability. It is a little on the pricey side, but I think its worth every penny!

I've had this keyboard for several years now and it has met every one of my picky desires - and then some. A few highlights that were particularly important to me:- Key spacing: Perfect, naturally comfortable.- Key travel: Awesome travel and just the right amount of snappy response.- Feel of keys: Smooth and great to the touch. Love it.- Full size keyboard with no number pad! Exactly what I wanted (as I don't use a dedicated number pad and it just serves to make the keyboard way to big and unnecessarily bulky and bloated, in my opinion).- Aesthetic: Clean, minimalist, simple, modern. Perfect.- Great backlighting.- Rechargeable battery: Long lasting between charges and no more wasted money on battery replacements (not to mention the environmental cost). Super convenient too. Thank you Logitech!- Speed: I type way faster and more accurately on this keyboard vs. any other one I've ever used (and I've used dozens).- Bonus: Dedicated Bluetooth buttons for using the keyboard to type on other devices. e.g. What a pleasure tying on this keyboard to write text messages on my Android phone.Seriously, I would give this keyboard 10 stars if I could. It's really that good.

This keyboard is great. I use it with my tablet and laptop and carry it in my bag. Price was great and ended up getting a couple for work for myself and a coworker since they liked it too, backlight is very useful, battery life is great, compact and light. If you aren't concerned with a num pad then this is a great keyboard for the price.Being bluetooth makes it really handy since you don't need a pairing usb adapter. The only problem with the bluetooth is that is your computer goes to sleep, it takes a few seconds for it to connect, though this might be more to do with the bluetooth module on the computer.

What a great keyboard.Had bluetooth products before and I always found bluetooth to be a little quirky when the device (mouse) would try to wake up and try to connect. There was always this long delay for discovery.But this bluetooth keyboard has totally changed my view on BT connectivity. I added my laptop, my cellphone and my main desktop PC and the keyboard switches back and forth seamlessly.The Logitech software SetPoint only allows re-assignment of 3 of the keys.While would like to see more available keys to use it's all good.
