This was my first Roku device. I was searching for a way to stream my Comcast to my outdoor backyard tv and this gets the job done. There is some buffering that occurs but that is more of a function of my wifi environment. The interface is easy to learn and use. The HD/4k streaming is awesome. My only concern is that the stick gets really hot. I've gotten a few on screen warnings. My TV is outside in a very open environment and it still gets really hot. Worries me a bit.
