Wireless Bluetooth Mouse with Smart Flying Scroll,Side Thumb Scroll Ergonomic Mice,Silent Multi-Device Mouse for Computer,Laptop,iPad,Tablet,MacBook (Black)

Compared to the Logitech M310 that I was using before the Infinmind L910 is night and day better. The thumb buttons and thumb scroll at this price point are what attracted me the most. Very comfy, useful extra buttons and side scroll for work/productivity, thumb rest, soft quiet clicks and extra weight due to 2x AA batteries make this a solid feeling and functional mouse. Also the Bluetooth connection frees up a USB port especially for laptop users.

This mouse reminds me of my old Logitech mouse with the hyper-scrolling feature. Unlike the Logitech, the scroll wheel is always fast-scrolling without the ability to turn it off. The wheel on this one also has a bit more friction, so it can spin a maximum of ~2 seconds versus the Logitech which can keep spinning for quite some time. This middle ground is quite nice since you can still use the wheel normally, only losing tactile feedback slightly compared to a regular mouse.The mouse buttons are not silent, but they are about half as loud compared to my TeckNet mice. The mouse has a horizontal scroll wheel that I feel wouldn't be used all that much given its position and the lack of pages requiring such scrolling, but it might be nice to have for large spreadsheets. The middle wheel sometimes makes a scratchy noise as you scroll, but this does not seem very consistent and is not too loud.The backward/forward buttons worked expectedly on my Windows 11 device where the button closest to you initiates a back action and the one up front initiates a forward action (as expected). It seems like the company makes two models of this mouse, where the black/white models have a manual mode adjustment button on the bottom and the gray one does not (automatic selection). If the wrong mode is selected (you selected Mac OS instead of Windows), sometimes the back and forward button may result in the emoji panel being opened instead of going forward/backward on pages. Changing to the correct mode should fix this issue.The grips are nice and have a rubber ergonomic feel on both sides (left and right). Unlike the TeckNet models, they do not have little grooves in the rubber where debris can be trapped inside these grooves (it's just one smooth rubber surface).The ability to select between 2 different Bluetooth devices is unique, and I don't think I have seen this feature on a mouse with this price point. Having a 2.4 GHz dongle option definitely is helpful when you are in a situation where you are working on a device that does not have Bluetooth or cannot install any new drivers. The mouse allows you to switch between these profiles by clicking on the selection toggle below the DPI button, which has tactile feedback and is not easy to press accidentally.The DPI switch works nicely and just like my old TeckNet mice, they allow me to fly through multiple monitors with minimal effort without flicking my wrist too much. This was also something that drew me to TeckNet in the first place (especially given their prices).One thing that really irked me about my TeckNet mice is that over time they seemed to have degraded in their quality. The TeckNet BM308 was an awesome mouse that had excellent battery life, but it ran on an older Bluetooth standard that tends to have issues while being paired with a headset that uses Bluetooth 5.0. The TeckNet EWM01308 uses BLE and promises 2 years of battery life, but I can barely get around 3 months of battery life before the battery gives out. The EWM01308 also seems to keep disconnecting and has connection stability issues. In addition, half of the EWM01308 stock I have tried cannot track on satin surfaces that have a slight sheen on them. It just keeps skipping movements which makes using them extremely annoying without a mousepad.When searching for a replacement, here's my criteria for what I am looking for:1. An ergonomic mouse shaped for the right hand, and is suited for large hands (which this one is).2. Has sufficient weight to it and does not feel like hollowed-out plastic when I move the mouse (this mouse has decent weight, especially since you can choose between 1 or 2 AA batteries).3. Has the backward/forward buttons on the left side of the mouse (which this one does).4. Has a sensor that allows tracking on satin surfaces without skipping or disconnecting (this mouse tracks on my white IKEA table without any issues or mousepads, and I have not had the mouse do funny jerks or disconnections on me yet - the mouse does have a red optical sensor like the TeckNET EWM01308, but it certainly tracks better than the TeckNet. It still wouldn't track on highly reflective surfaces, like glass, for example.)5. Has a good level DPI that allows me to fly across multiple screens without too much movement of the physical mouse.5. Has a battery life lasting over 6 months on NiMH 2xAA or internal rechargeable batteries (will talk about this later).This mouse meets all of the above criteria and offers a bit more (2 BT profiles + 2.4Ghz dongles), hyper-scrolling wheel, and a horizontal wheel.On the topic of battery life, I am a little bit disappointed by the fact that there isn't too much information about the power consumption of this mouse, except the fact that it lasts 40 months on 2xAA batteries. Because of that, I decided to whip out a multimeter and an adjustable power supply to give this a test.Like the TeckNet EWM01308 mouse, this is also a Bluetooth Low Energy (BLE) mouse and reports battery levels back to the device. As expected, the device does not provide any granular battery percentage levels, but instead, the battery percentages were mapped back to a number as the voltage crosses a specific level. Here are the levels that it reports:>1.4v - 1001.4v - 751.3v - 501.2v - 251.1v - 10 - Low Battery Indicator On1.0v - 50.9v - 0Out of the box, it comes with 2 alkaline batteries with a separator tab to prevent parasitic draw. The batteries out of the box were at 1.62v, which means they were quite fresh to start. Until the batteries get drawn down below 1.4v, the device will keep reading the battery level at 100%, then drop to 75% as soon as it falls below that level. This means you will never see battery levels like 98% or 95% since the device never gets that granular.When the voltage falls below 1.1v, the device selection light will blink as you move the mouse. On the BT 1 setting, this light is blue and has no specific red color for low battery. But you will know it is low battery since the blink happens frequently as you move the mouse. The battery levels are perfect since they are within the NiMH operating ranges, where a full set of NiMH rechargeable batteries will read 75-100%, with most of its useful life reading ~50%, then dropping to a 25% reading when the NiMH is more or less depleted and requires a recharge. The 1.1v level also represents a good level for NiMH without consistently nagging the user that the mouse is going to run out of power on a reduced voltage. Under the 5% reading, Windows 11 also popped up a warning saying the device is critically low in battery. The device will function at 0.9v, but will turn itself off when idle to prevent excessive battery drain. This is excellent for both NiMH and alkalines to prevent battery damage or leakage.Unlike the TeckNet mice which are wired in series and operate at a 3v voltage level, this brand wires their battery compartment in parallel, which means you can choose to run the mouse with either 1 or 2 AA at a lower battery voltage level.When the mouse boots and tries to establish a Bluetooth link, it draws approximately 10-20mA of current when measured at 1.26v (median NiMH voltage). During mouse movements, the draw is around 4-8mA, depending on the duration and complexity of the movement. It quickly drops to ~1mA after movement stops. After around 3 seconds of being idle, the power draw drops to around 0.5mA. After 20 seconds, the optical sensor enters a slower blink rate, and the power drops slightly more to around 0.3mA. After 10 mins of being idle, the mouse disconnects its BLE link, and the power current drops to 0.005mA (5 microamps - the mouse continues to blink its optical sensor slowly, which means you can quickly re-establish the link with just a move of the mouse).Unlike many Bluetooth or RF mice that require a click or a quick movement of the mouse to wake it, this one simply needs a normal move of the mouse to wake the computer up. I have not had it either being too sensitive or too insensitive that I find it to be an issue. It was just right and so far I have not had any reconnection issues, which seemed to be an issue I find with the TeckNet EWM01308 quite often.The TeckNet EWM01308 draws slightly more current while in operation, about half of the current when it is in light sleep, and the same about of current when in deep sleep. However, because the EWM01308 is wired in series instead of parallel, it reflects double the voltage, which means overall the mouse draws about 2-3x more power than this particular model in its operation.The BM308 uses the same deep sleep power as the EWM01308 immediately once mouse movement ceases, but uses significantly more current (15-20mA) when the mouse is being moved. That being said, this is still at double the voltage that this particular mouse operates under.With that said, it is unlikely you will get 40 months of battery life on this mouse unless you use your computer for like an hour a day at most and turn your mouse off when you are done using it. If you are on your computer 10 hours a day, you are likely only getting around 5-6 months of battery life, assuming you leave the mouse on 24 hours a day without manually turning it off and using both batteries. With lighter use or movements, it is quite possible to get 10-12 months of battery life on this mouse, even if you do not turn it off during extended non-use.I think this is a good compromise that allows you to simply wake the mouse and device up by just moving the mouse and not any additional click of buttons, yet not drawing too much power at the same time. Even at 5-6 months of battery life (on NiMHs), this is still decent enough that you only need to charge these twice a year on heavier use. Of course, this also depends on the quality and capacity of your NiMHs and whether they are low self-discharge (low LSDs). But running them on IKEA LADDAs should give you decent battery life such that you don't have to keep recharging the mouse every month or every other month.

Overall very good in every way. Size, weight, and features are all excellent.All buttons are great, quiet, and click very well. Setup is a breeze, and everything works as expected right out of the box. I thought I would want a rechargeable mouse, but really it doesn't matter much. It says the batteries will last over a year, and that's plenty for me. Also, it's way faster to swap batteries than to recharge anyway, so not a big deal.One REALLY nice feature is that you can run on either one battery or two! You choose! I've never seen another mouse give you this option, and it's an excellent idea! It gives you a little bit of control over the weight of the mouse, and adding the 2nd battery doubles the battery life!My ONLY complaint is the position and function of the horizontal scroll thumbwheel. It's too high, and using it takes some getting used to. Also, unlike the vertical scroll wheel, this is not a "cruiser" style wheel... it has the normal "stops" and is a bit harder to work, especially with your thumb. I would have preferred it to be a free spinning wheel like the main scroll wheel, and positioned lower on the side.For under $20, you will not find a better mid-tilt ergonomic mouse. Period.

Great mouse! I use this daily for work and couldn’t ask for a better wireless mouse. It doesn’t feel cheap or lightweight it feels expensive and comparable to other big name brands. The size fits perfectly in my hand. I’ve never had any connectivity issues and have never had to change any batteries. Super great to use and would recommend everyone pick one up for their daily driver.

...one star it is.Let's start with the instructions. They are your typical, nearly unintelligible instructions. You learn to deal with that. BUT they are printed in ... what?... 4pt??? And in low contrast. So, for what they're worth, reading them is nearly impossible anyway.Now on to the Really Bad Design Feature:There are two poorly placed and overly sensitive buttons on the left side of the mouse. The function of the front one is a mystery. For example, if it's pressed while the cursor is in this text box, it does this: '''''''''''' (Why do I need a mouse button that gives me a bunch of ''''''''''''s??? See? A mystery.) But at least I don't hit this one accidentally.The function of the back one is all too clear and extremely obtrusive. It triggers an emoji popup menu. (Is this for real? This can't be for real, can it?) My thumb accidentally hits the stupid thing EVERY TIME I roll the horizontal scroll button down to scroll right. It's extremely annoying since I have to get rid of the popup before moving on with whatever I actually meant to do.Sooooo... INFINMIND, is there a way to disable this button? If so, I'll gladly disable it and change my review to ⭐⭐⭐⭐⭐ (<----see what I did there? My one and only intentional use of that stupid button!) and keep using this otherwise-okay mouse. If not, back it goes.
