We have had no problems with the Roku stick itself and enjoy it immensely. However, we have had no luck with either the remote control that came with it or a replacement sent by the company. First remote is completely dead. Second will pair with the stick and hold it for a few minutes and then lose connnection again. As a result, we have to use the Roku app on our phones for a remote which is kind of a pain.
I purchased the stick so I would be able to use it in different rooms. It works really well and I am happy. The only issue is that the remote doesn't work sometimes but it's rare.
First Roku Stick failed when HDMI cable kept falling out. Returned to store for replacement. 2nd Stick had issues with WI FI connectivity and way too slow. Returned 2nd unit and went with another manufacturer.
The stick is like a half broken Apple TV. The apps crash all the time and the interface is slow and the remote is cheap. Save yourself some money and get a chromecast or get an Apple TV. The only good thing is that I can watch nbc sports on it.
