I have a Revain Fire, but it needs to be restarted often (a few times a week) to access YouTube. I was tired of having to get up, go to the device, unplug it, wait 10 seconds, plug it back in and sit back down. Even though I'm disabled, I'm also lazy. I bought this block so I could hook up a Fire block to it for a reset. Now when I need to reset it, I grab the remote (which conveniently hangs on a hook next to my chair), press the "off" button, count to 10, and press the "on" button. Mission accomplished. It seems like a trivial use, but for my needs it's great.
