We plan to drop cable so I bought the streaming stick for our bedroom television. The Streaming Stick works quite well. It is not as fast as the Roku 3, but I am satisfied with it.
I've had my old Roku for about 2 years and have no problems with it. Recently my ISP has been slow and that has caused Netflix to drag on the Stick, but my old Roku still streams it fine. Otherwise the stick works great.
I bought the newest Roku for my primary tv after breaking free from cable tv. Couldn't be more pleased, so I got the stick for another tv. Just plug it in like a flashdrive. Perfect!
