It does what it says on the tin, a brilliant piece of kit. It's a pity the remote control keeps locking up though, I have to remove a battery to get it going again.
The only issue I have with this Model is the remote control. it disconnected from the stick several times and I had to re-pair it. it didn't happen with the other Roku 3 model I have.
After a shaky start the Stick is working fine most of the time. Occasionally it doesn't respond to the remote, so I have to go through the resynch ritual that I had to Google to learn how to do. Worry that the Stick stays rather warm to the touch while connected to the power supply. Rather was turned off at first with the menu screen, as it differed from the Roku 2 format, but after the mental adjustment, guess it's now fine.
