I have 2 4k Firesticks for 2 TV's one is used heavily, sometimes it has issues but a simple unplugging the power cord and replugging it in solves the issue. HBO Max app is pretty nice picture on it. I prefer the FS 4k over the Roku 4k premiere. But I've noticed the Roku picture quality is improving. If Firestick 4k or the cube is on sale on Prime day I'll probably get another one. Maybe HBO will be back after July 4 long weekend??? Or when Dish release's their new hardware.
Interesting... I've had Roku sticks ever since they came out and none of them have ever failed; I've only replaced them to keep up with current streaming technology. I do have a Fire TV as well but it's built in to a Toshiba TV I bought for the bedroom, not a stand alone unit.Darn good question. They were both years old and neither has any way to turn it off. I have a 3rd which has spent most of it's life in my luggage, and it was still working the last time I took a trip.
Our most heavily used Stick kept losing it's wifi connection and had a tough time getting reconnected after a reset. The second most heavily used is stuck on the FireTV animated logo. I have not been able to get it to do a factory reset, so it's headed for the trash as well.
And now I"ll say something really shocking to get somewhat back on topic. I am using my J3 almost exclusively because of that stick stuck in boot. Our Dish gear are all on all the time as well, with no such failure.
