As someone who has been using HTPC's, Kodi and android boxes forever I have always struggled to find a remote that can handle all the various functions of these devices. Up til this point the best controller I had found that wasn't absurdly large or clumsy was the Rii Mini x1 (2.4ghz) but that came with it's own set of flaws. Rii has knocked it out of the park with their latest product the Rii MX6 is truly great thus far. Using 2.4ghz with replaceable AAA batteries and IR learning w/ a full keyboard and air mouse is key to ease of use for my nvidia shield. I use Kodi and Live Channels app to watch content from my HDhomerun Prime and having number keys on the front of the controller is a godsend. So far I absolutely love this little device and if anyone is looking for a more robust remote option I highly recommend this device
SPAM. This guy has been spamming his overpriced Amazon seller link for a week (check the seller account, its brand new). He'll make a post, then delete his activity so you can't see his post history. Needs banned.
