I bought the Roku stick about a month ago and we absolutely love it! The portability is great and the features are awesome! The only downfall is that the power cord does not stay tight into the stick, so we had to tape it, even brand new.
We have been using this for a few weeks, and I really like to device and set-up. Easy to use, and seems to use less data than the firestick we had been using....
The mini usb power connector head turned loose quickly after the 2nd day of use and failed since then. I had to use my phone's mini usb cable for that.
Usually watch movies. Have a Roku 1 for another TV - good performance. The stick is much simpler because no wires. Interesting - I just got a smart tv to watch movies. Had trouble with too much buffering. I think the tv was too fast for my network. After many attempts to boost the network, I decided to try ROKU in front of the tv - bingo. Good solution for reasonable $.
