I have one Roku 3 and three Roku Sticks. The remote control is crude, and the response is slow. Roku needs access to ESPN for sporting events. Other channels, such as CNBC and Hallmark, would also broaden the appeal.
The Roku stick works great at receiving wifi. I have a Smart TV that cannot receive wifi because they are to far away from the router. The Roku was the answer - it has much stronger reception (much like a PC has a stronger reception that Smart TV). Well worth the price.
Bought the Roku stick for my son. He's able to use in his apartment outside of campus to get everything we get at home. He's thrilled with it and saves him a large cable bill.
Bought this for my son for Christmas to turn his 1-year old HD TV into a Smart TV so he can access Netflix, Pandora, etc., and it works like a charm. Picture and sound quality are excellent. The TV only had 1 HD input, so we also got a splitter and he is able to switch very easily between Roku, our digital cable provider and his X-box. I am decently familiar with electronics, but by no means a techie, and I found installation/set-up to be a breeze. The product description seemed to indicate that this stick did not come with its own power source, but it does - even better! I would highly recommend this product. Thank you, Roku!
