I've had this streaming stick for a few months. It came with Duracell batteries that died very quickly, and when I change between apps or episodes I get a black screen often and have to hit the home key to start over. That becomes frustrating after a while, but other than that it's a nice streaming device, I would recommend it to people with patience.
The service and quality was about what I anticipated. I also own a Roku 4. I switched from cable to save money and to watch movies and sports. My biggest complaint is I can no longer sign into NBA league pass. I have the NBA team pass (Just one team access) and that worked on the Roku till a month or so ago.
