I bought the ROKU stick four months ago. I installed it easily myself. I love watching Netflix and PBS. I signed up for HULU, but dropped it after two months as it didn't load reliably. I am hopeful that more channels will be available through streaming. It is a great product.
This is actually the second Roku streaming stick I've bought. The first one went in our master bedroom. We found it so useful that we put one in the living room. The picture quality is great, the remote is easy to use, and anything we want to watch is on Roku.
Already have a Roku 3, decided to try the more compact Roku streaming stick, although it is slightly slower than the Roku 3 it is just as easy to use. Would strongly recommend.
