I bought the Roku Stick on vacation. The video quality is generally fine, but the remote control has problems with keys sticking (so when I press once to move over, it keeps moving), or failing to respond to key presses.
I bought new batteries, thinking those supplied by Roku maybe were old, but continue to see the same problems with the remote control keys.
I have a Roku 3, and wanted a streaming stick for another TV. The one I bought was defective - the remote did not work properly. I had to return it and get another from the store. The second one does work properly, and I am enjoying my Roku-provided programs on both TVs now.
I bought the stick about a month ago and loaded it promptly. Everything was easy. The only issue was that the selection of the TV vs the Roku "channels" was a bit different than my Roku on my main television, so that had to be figured out. But be prepared to have your internal network and Netflix passwords available to speed the process.
Got my Roku Streaming Stick from SlingTV and had it up and running in minutes with my existing Roku account. Very nice to move from TV to TV. Only negative is having one more remote to keep track of.
I love that this thing connects to so many services. However, I may have to toss the thing if I can't get the remote to work consistently. Often I need to remove the batteries to get it to start responding.
