New Dual Mode Wireless Multimedia Keyboard with Touchpad Mouse Rii I4 Bluetooth 4.0 with 2.4G Wireless Mini Keyboard with Scroll Button LED Backlit Rechargeable Battery

Perfect, easy connected, easy to use and works really well with the Pi 5. Battery life is great and mouse features are a nice extra.

Sensitivity of the touch pad could be better as it's not super accurate like a modern phone touch screen or laptop touch pad, and I'd like a mouse button under the touch pad so I can use one handed. Some of the keys are in different places to what I'm familiar with, like the apostrophe symbol. Apart from all that, it's a great device that turns my TV into a media PC when paired with my laptop. It goes to sleep after a few minutes, but that's probably a good thing to save battery life. You can easily switch it off and on to wake it up. The red scroll wheel is really useful and works well. Volume control is also useful. The shoulder buttons act as left and right mouse buttons. The d-pad is like the arrow keys on a keyboard. I haven't tried Bluetooth, I just used the USB dongle and it worked straight away on a Linux computer with no need to download any drivers.

If you want a compact keyboard / mouse solution this seems to be a solid option, bumper mouse buttons are nice, backlight makes it easy to use in the dark, internal battery has decent life with usb-c charging, easy BT / 2.4hz mode switching allowing connecting to two devices is nice. The soft keys have a destinct click so it doesn't feel mushy, not something you'd want to type a lot on, but good functionality for it's size and price.

Works really well. Feels good and quality is good. I use it with a Raspberry Pi - perfect. Such a small keyboard is always going to be more tricky to type with howver this does work. Built in mouse pad works well and the scroll wheel and cursor keys are well positioned. Wish I'd bought this a long while ago. You wouldn't want a smaller keyboard for sure but a bigger one would make it more difficult to hold in the hand. Great size.

I bought this initially based on a review which said it was pretty decent for use with the Steam Deck. They were right! This thing works flawlessly with my Deck, i don't bother with the transmitter either as the bluetooth works so well. I used this to help me get my emulators and retro games all set up properly, and continue to use it all the time. The battery life seems pretty decent. No issues here. It has a built-in power save/sleep function which clearly helps it a lot. Some people describe this as a pain, but, the alternative would be the device staying perpetually "on" and i bet the same people would then be complaining here about it needing too many charges. To wake from sleep press any button and it will automatically reconnect to the device (quickly too). The layout of the device is really efficient: - the scroll wheel feels great and works like a charm. - the left and right shoulder buttons act as left and right mouse clicks (my preferred way of using the deck is holding it like a controller, using these shoulder buttons with index fingers, whilst thumbs use the touch pad). - the touch screen/pad is responsive, and you can scroll a lot more quickly and accurately with this if you practise (and with a quick button combo you can increase sensivity). - You will quickly develop muscle memory with this; i can now type pretty well and control streams without even thinking. Other places this controller has shined for me: - taking it to social gatherings so i can quickly get Steam party games set up (like jackbox). - couch/bed streaming - I actually use this with my desktop PC all the time, so i can sit back and relax in bed whilst controlling series/films etc. The tiniest of negative points: You won't be able to tell from your connected device how much battery this thing has left, it seems to always say 99% when i check on my PC or Deck. However, i hear this is quite a normal issue with all sorts devices simply not supporting this feature.
