Wireless Air Mouse Remote Controller, Rii MX8 2.4G Wireless Multifunctional Air Mouse Control,with IR Learning and Voice for Smart TV XP,Windows,Android and More Media Player

I was worried that it might be too big/bulky, but it's actually pretty compact, and fits my hand comfortably. It's about 6 inches long.Build quality is excellent. It feels solid and durable. And I don't know if it was intended or by design, but the remote is weighted in such a way that you can easily tell if you're holding it upside down.Scroll wheel is pretty cool and useful.I use it on my Ubuntu machine, so ended up using udev hwdb rules to remap a number of the keys to work better as a media playback remote. You can use evtest to find the key values that are being sent by the Rii remote, for remapping purposes.The little user manual that came with is terrible. Tried using it's directions to program the 5 programmable IR keys, so that I could use this remote to control my television, but the directions were so badly written that I was unsuccessful at it. Finally, I looked over some of the reviews here on Amazon and a user had written some instructions which I was able to use, to successfully program the 4 color keys + the greyish blue power button in the upper right corner of the remote.I added the following television control functionality to my Rii remote: 1. television power on/off; 2. television volume up; 3. television volume down; 4. television input menu; 5. television select/enter. This covers 99% of what I used my television remote for, so I can now use my Rii remote to control my television and stash my television remote in a closet.My one concern, at this point, is that there is a little blue led light that stays on for about 30 seconds whenever you press a button on the Rii remote. Worried that this might adversely affect battery life. I'll try to update this review if I encounter any significant issues with the battery life.BTW, here are my instructions on how to program the 5 programmable IR buttons on the Rii remote:How to program the 4 color buttons and the greyish blue power button:1. Hold down the color button that you want to program. It will blink quickly for about 3 seconds. When it stops blinking and shows a steady light, release the button.2. At this point, within the next 10 seconds, point your tv remote's ir transmitter to your Rii remote's ir transmitter/receiver and press the button on your tv remote that you want to program.3. If the Rii remote received the signal, it will blink rapidly 3-4 times to acknowledge that it successfully received the code.4. Now test your Rii remote's color button, on your television, to verify that it programmed successfully!

Pretty good remote for $8. I use it with a Chromecast with Google TV (android TV) to replace the silly little included remote. Remapped the buttons with Button Mapper app.The mic DOES work, but the mic button does not send a button press event. You must map another button to trigger the Google assistant, and then HOLD the dedicated mic button on the remote for it to pass your voice through. Sort of annoying, but also somewhat comforting that the remote isn't capable of listening 24/7.The big cons to me are that it has a blue light that never shuts off, and it can be slightly bothersome at night. The mouse function is nowhere near as smooth or accurate as my LG magic remote.Most LG TV's have IP control, and you can use Button Mapper to send netcat commands to open the brightness settings or change volume or whatever you want. I mapped the top colored infrared buttons to my LG air conditioner. Sound bar and power controlled via HDMI-CEC. Now I really can just use one remote for everything.(As a side note for those with an android TV, I mapped the page up and down buttons to the TV Volume control using IP commands. The native volume buttons control the chromecast volume. This allows volume control via Google assistant voice commands and volume reduction while speaking, while still allowing you to control the TV/soundbars actual volume. If you do straight passthrough, volume controls will control the TV fine via CEC but you lose out on assistant/voice control).

Before I got a streaming stick for the bedroom, I used this remote to control a Raspberry Pi 3B with LibreELEC flashed on its SD card! It has all the buttons I need, it works great, and the dongle doesn't consume enough power to overwhelm the Pi! Thought the "air mouse" feature was going to be gimmicky at best, but I've used it more than I thought I would, and I love it! Mic button doesn't work on this platform, but the IR power button is a welcome addition, as it allows me to turn the TV (which does not support HDMI-CEC) on and off as well! Great value for the price!
