This device was acquired with the intention of watching Netflix and Youtube videos on a non-smart TV, however the streaming quality was way inferior than my Smart TV and my PS4 that were connected to the same wifi in the same room. None of the devices were 4K. While the others had no problem to stream in HD (1080p), the Fire Stick could keep only half of that. A really poor image quality.
The good part is that it was easy to get a refund from Amazon, so maybe it's worthy trying.
Good performance, but the remote control's quality is low. I bought it less than a year ago, and the remote control only turns the TV on and off. All other features are lost. I will have to order a replacement, which is quite costly if I have to keep doing it every year.
