2.4GHz Backlit Mini Keyboard Touchpad Mouse, Mini Wireless Keyboard with Touchpad and Multimedia Keys for Android TV Box Smart TV HTPC PS3 Smart Phone Tablet Mac Linux Windows OS (7 Colors)

Works great on my raspberry pi 4 and on my smart tv.

I uploaded a video demonstrating the colors but I don't see it listed so I'm writing a review instead. So please excuse me if this is posted twice.This thing is great. It gives you the option of the removable lithium-ion battery or to Triple A's. It's lightweight and compact but not too small. It is the perfect size. I have a terrible time with typos on my Android phone because my thumb takes up like six of the keys at once. With the USB to micro-usb adapter that I got from Amazon I can use this lovely device on my phone.Now, the product itself doesn't feel like it's built that strong (because its so light) but that does not take away from its performance whatsoever. I mean, I wish the back was a little grippy but with the contour and size of this device, theres no way you will drop it.I seriously have no complaints whatsoever.But I will mention that the device I got only has three colors (as shown in the video that I uploaded.) Not that it matters to me because when I use it during the day I have no need for a backlight.I highly recommend this product.I also highly recommend picking up the USB to micro-usb adapter to use with this on your smartphone. I got like four of them for $4. It will enable you to use a mouse and keyboard on-screen. It navigates beautifully on my android phone.

I've bought this kind of keyboard many times before. They generally don't last. This one has been going strong for over a year so far. It is not the highest quality product.. requires line of sight to the receiver .... But it's a great keyboard for the bed or couch

A piece of crap that stops working after 1 week. Save your 10 bucks because it will turn into 20 and so forth when you get new ones. It's exactly what I needed except its cheaply made. My mouse pad became fidgety and made my cursor jump all over the place on my screen. I could never click anything and the buttons will begin popping out. You can put them back in, but its just irritating. I'd consider it worth a try if you drop the price down to $2

I love this little keyboard with mousepad. It works so good for when you just want to sit back in your seat and check things out on your computer.

PROS: I was pleasantly surprised by the remote at the beginning. It reminded me a lot of the Rii 2.4GHz Mini Wireless Keyboard (https://www.amazon.com/gp/product/B00Z81U3YY/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1), which I had once owned and enjoyed. The awesome thing about this remote though, was its price. It's half the price of the Rii which is the reason I decided to buy it. In terms of feel and build quality, it was comparable to the Rii though slightly below. The Rii has a rubber-like feel to the casing while this remote's casing is your basic hard plastic. I don't want to give the impression that it's chintzy though, because it felt solid and took several drops. The buttons were impressively just as good as the ones on the Rii model if not better because of the white colored edging which helped you distinguish one button from another (see pics). What I also appreciated was the bezel separating the track pad from the casing. I've owned other wireless keyboards, including higher end Rii models, where the track pad is simply part of the casing and invariably you end up touching it all the time which gets annoying. What was definitely superior in this remote compared to the Rii was the charging cable used. This remote can be charged by any old USB micro B charger which everyone has laying around from their old phones, while the Rii uses the more obscure mini B. What's more, this remote was plug and play just like the Rii.CONS: To be honest, this remote and the Rii model are so similar that I would have to say one is a knockoff of the other. That isn't to say that knockoffs are bad, they sometimes can be better than the original, but in this case there are some glaring problems.The first problem was the battery. The Rii model has an internal rechargeable battery, this remote has what looks like an old flip phone battery that was shoehorned in to the back. The charge on the battery lasted a few weeks the first time, so that was good, but eventually in subsequent charges it would last less and less until it eventually died. This of course happens to all chargeable devices, but the problem was that I only had this remote for two months before it died.The second problem was the deteriorating nature of its wireless range and key inputs (button presses). At first you could hold the remote in any direction and get the device (Nvidia Shield in my case) to register an input. I live in a small apartment, so I cannot speak to the distance too much, but I remember being in the bathroom and controlling the TV from there (yes, I know this is disgusting). But as time went on I noticed you had to sometimes press a key two or even three times to get an input to appear. Also, if you weren't pointing the keyboard towards the device it would sometimes not register at all.OVERALL: Great price, good initial quality, poor durability in battery life and hardware. It lasted two months. Just spend the extra 10 dollars and get the Rii which this device is a clear ripoff of anyways.

Works fine. USB C charging!!!

I thought it was a joke at first because it's so small but I plugged the USB in, it was connected to my Samsung TV, and it grew on me right away. It's easy to use and tuck out of the way. You can keep the backlight on and changing colors (See YouTube video) which is a really cool effect when watching in dark. I love not having to scroll through my Samsung alphabet with the remote control anymore. Both work at the same time so I use whichever is more convenient. First time I couldn't find the remote this thing proved it's worth. There are a lot of buttons on here and I will probably be figuring it out for years but I was able to learn 90% of what I needed just by looking at it. I'm pretty happy with it so far. Good battery life. I charged it when I got it 4 days ago and it's still working fine.
