I've been using my Roku stick for a few weeks now and I am very happy that I purchased it. I love the convenience of the small stick and not a box modem. Makes it very easy to switch it from the living room flat screen to the bedroom flat screen. I have no complaints about it.
We love our Roku. Unfortunately we left the remote in a vacation rental we stayed at in California. They have yet to send it back to us, so our Roku is not operational at the moment. Are there sites where we can buy another remote? Sure hope so.
I bought a streaming stick when I got my new TV and I have been satisified since. The only problem I had was setting it up. You have to figure out which site to go to.
