After trying a Logitech K400 keyboard and becoming frustrated with its quirky key layout, I decided to try this. As you can see from the listing photos, it has an almost standard key layout. I also checked the reviews and discovered that (unlike the Logitech) you don't need to press the "Fn" key to access F1-F12. But I discovered a few more advantages:First, the keyboard is in a sturdy metal case. (The wireless radio is in a smaller plastic case underneath the keyboard itself, so the radio waves can get in and out freely.) Not only does this give the keyboard a much sturdier feel, it gives it extra weight so it doesn't slide around your lap much as you type on it.Second, although the keys are "chiclet" keys, they have even better tactile feedback than the Logitech (which wasn't bad).The keyboard is full-size (the Logitech is close, but not quite full-size), which leaves less room for the touch pad. So they mounted the touch pad sideways (it's taller than it is wide), letting the whole thing fit into the same width as the Logitech. (The keyboard's height is actually smaller than the Logitech.)Speaking of the touch pad, the Logitech's was pretty good. This one's even better. It's bigger and has a "scroll bar" at the right, so you can scroll with one finger. (Two-finger scrolling, supported by most touch pads, also works.)Unlike the Logitech, this keyboard doesn't need batteries - it has a rechargeable battery built-in. A charging cable is included, which also contains a USB extension, so you can charge the keyboard without blocking a USB port. You can also use the cable as an extension for the keyboard's receiver so you can put it closer to where you sit.Now for the drawbacks: First, the charging port is one of those dreadful micro USB ports, which are renowned for breaking after being used repeatedly. And if you've ever had to have one of these repaired on a cell phone, you know when it does break, a repair won't be easy and would probably cost more than a new keyboard! They should have used a small cannon plug for recharging instead.Second, touchpads, no matter how good, are terrible replacements for mice! It's all but impossible to position the cursor precisely, and it's always accidentally clicking things when you're pressing keys on the right side of the keyboard and a finger accidentally touches the pad! (Slowing down the pointer with the mouse control panel helps.) A trackball would have been a much better choice.Finally, the keyboard layout could still be improved. The "Insert" key is Fn+F9, which is awkward and I kept pressing other combinations like Ctrl+F9 or Shift+F9 or Alt+F9 by mistake, sometimes with disastrous results. Also, F12 is just about where F11 is on a standard keyboard, and the Delete key is just about where F12 is, resulting in frequent mistakes here too, again sometimes with disastrous results. They would have been better off moving Insert and Delete down to the left and right of the up-arrow, and spacing out the F1-F12 keys as they are on a standard keyboard.Still, this is a better-than-average keyboard at a good price. Maybe they'll come up with a new version with the improvements I suggested above someday; then it will be even better!

I will also note that I am typing this review with the Rii K22, and I can say it is a very usable experience. I'm not typically a membrane keyboard kind of guy (mechanical is my go to) but this little guy really is really great in many use cases. I originally purchased this product, so I could navigate my YouTube while lying in my bed, as my desktop is connected to my monitor and my separate TV. I can confirm it works great for this with a great range and very usable responsiveness. I then moved on to using it for casual web browsing and entertainment watching while laying back in my computer chair where I wouldn't normally be able to comfortably reach my keyboard and mouse, and this is how I usually use the K22.The keyboard switches are very passable for this price point and use case and have very good travel for a membrane board, but the trackpad is really where this product shines in my opinion. When it comes to mobile computing I use a MacBook Air and the trackpad on that things I believe is industry leading. In the off chance I would use one of my peers’ windows laptops the trackpad never lived up to the smoothness of operation and multi touch responsiveness and accuracy of the apple made trackpad. So, with that said my expectations for this trackpad were low but I was pleasantly surprised. This pad is fully equipped with multi touch and tap operation functionality: one tap single click, two tap double click, two finger tap right click, double tap and drag to highlight, two fingers moving vertically page scrolling., fingers moving away or towards each other page zoom. There are also capacitive volume controls on top of the trackpad, as well as a vertical scroll bar on the right long edge for single finger scrolling. There are a left and right click button below the keyboard, but they are a mushy unresponsive mess that requires a lot of force to activate, however I don’t find this to be a huge issue as the tap clicking functionality works so well. The last con I can think of for the trackpad is its proximity to the keyboard, even though that is the point of the product. I have fairly smaller hands, so this isn’t a huge issue for me, but those with large hands may accidentally operate the touchpad while resting your fingers and typing on the keyboard, as the trackpad is about a cm from the enter button. Sometimes you tap the space outside the text entry box and interrupt your typing or accidentally open a new page, but these are all minor annoyances.I will end with the statement that this keyboard is for casual operation and should not be used for heavy typing use cases like typing school papers who writing reviews like this. While the keyboard actuates and responds on the display great 99% of the time, some users who can type fairly quickly will find that the keyboard struggles to keep up sometimes. The aforementioned trackpad issue of unintended taps and touches is also a problem for serious word document processing because you could move your text entry point to another part of the paper, interrupting your writing flow and forcing you to correct the error. This keyboard is amazing for a wireless and casual use case, and I think its price reflects this quite well and fully recommend this product

Overall I'm reasonably happy with this. For the price, it feels pretty nicely made, and the overall aesthetic of it is good, and the overall functionality is nice. It's great having a keyboard and touchpad in one package, and it gets the job done.If you need a backup keyboard, or a keyboard for a system you don't normally need to type on, it's good. The keys are laid out in a familiar shape and size, and the touchpad is a decent size too. For that kind of usage, it's really hard to beat.However, I would not recommend this as your daily driver. It's "fine" but it just isn't quite up to the task. The keypresses aren't the most firm feeling so you can end up missing keys pretty easily, the touchpad isn't the most reliable for dragging, and the buttons for the mouse require a weirdly long push. If you tried to type a paper on it, I feel like it would get frustrating.Still, for $23, next-day shipping, it's a pretty nice little keyboard for the right use case. I definitely recommend it if you need a backup, secondary, or less-frequently-used device. You get a ton of quality for the price, and it's far, far better than it should be. But if you need a keyboard to use every day, look elsewhere.

-1 star because touchpad had a bump in it like the adhesive was coming undone after the first use. I firmly pressed it back down and it seems fine now. Works as expected otherwise. Pretty good for the price, but it'd be great if they fixed the issue with the touchpad.

that if you do get it, it has an auto-sleep feature after a certain time. All you have to do when it goes to sleep (and it's to save you battery life!) is just click or press a key and your keyboard comes back to life!I read a lot of the negative reviews before purchasing this keyboard and heard a lot of negative feedback regarding battery life and it turning of suddenly. After using the keyboard extensively, I'd like to report that the people talking about the keyboard turning of suddenly are idiots, as for battery life nothing suggest that the battery has any problems.I believe most of the people talking about the keyboard's failure to activate is simply people forgetting that the keyboard goes into sleep mode if you are inactive.As for the battery life, well, I've been using the keyboard semi-regularly (about 2->3 times a week). I don't use it extensively (go on youtube, click and watch a video, the keyboard goes into sleep mode, finish video move on to next) in most cases, but in some cases, IE programming, I do type a lot. The battery has not been charge ONCE since I received it and used it... on Christmas. It is now February 13, fastly approaching 2 months, and I still haven't charged it. So as for battery life, I'm sure that every once in a while a bad battery is shipped, but I have nothing to report negatvily about the battery, just positives all around.The one issue I have with this keyboard, is that when I'm typing quickly and dishing out lines of code, sometimes if I don't press ALL the way down, the character I'm trying to print out doesn't work, and obviously the program doesn't compile. If you are typing quickly on the keyboard, you will have to press down ALL the way to get it to consistently press every keystroke every time. It might be because I'm just used to typing on a mechanical keyboard, but my laptop has a buttery fly style keyboard (much like this one) and doesn't have this issue.All in all though, for the price range, I am completely and utterly satisfied with this keyboard. If this keyboard was valued $20 above it's price range, I might have something to say about the key quality, but at this price anybody complaining either has a defective model (seems to be quite rare), or just wants something to complain about.
