I had a roku 3 for 2 years. When it got fried, I opted for the Roku stick as I did not need the additional features of Roku 3. What the description failed to mention is how slow this device is, and I am not talking about startup or booting times. I am talking about how annoyingly slow it is to navigate in for example netflix to select a movie or a tv show. I am giving it a 2 star. For what its worth, I gave the Roku 3 5 stars. Do not go cheap like me :)
I bought my stick in Nov.; and it has always given me problems with buffering, interrupting shows, actually going off then starting from the Roku dance. I love it when it works; but when it keeps going off, rebooting, and going off again over and over, it can be pretty aggravating. I also hate the weak plug that fits into the stick as it is so thin that it can't even support the weight of the small cord attached to it without loosening.
I bought the Roku and waited to install. I don't know for sure why, it sat on the shelf for 3 months. What a waste of time. Took 10 minutes to install and set up. I am in TV heaven. Best purchase ever!
