I love my Roku, however it is very slow. I just bought it in November of 2014 (so I've had it maybe a month) and my only complaints are that it is slow, and that I cannot get the remote to work half the time. I have changed the batteries, etc. but I still have to push the buttons very hard/move around to get it to work.
I have a basic roku box in one room, they are not available at best but any more so I bought the stick. Certainly not what I expected. It loads slowly, stops to buffer and some of the stations are not updated even though I did an update when I bought it.
