I use three different levels of Roku devices in the house, this review is for the Express edition. As a Roku, it is fine. As an add on device, it has issues. First, the remote is IR (infrared), which means you have to have line of sight between the remote the receiver to work. If you have a busy TV area, be prepared to re-design it to allow for lack of RF in the remote. Second, the included HDMI cable is very short, maybe 18 inches. So.....Roku first requires you to position the receiver to be visible to the remote but Roku then requires you do so within 18 inches of your HDMI input on the back of your TV. Oh, the fun. If you don't have a 6' HDMI cable, get one (adds another 10 bucks to the cost). Thirdly, the power cable is short. I think most people at this point have TVs mounted on their walls and so route their cables in a raceway or through the wall. If that's you, buy a 3 or 6 foot extension because you'll need it.
And the icing on the cake? The "I heart Roku" sticker of course. Swap the sticker for a longer HDMI cable when you ship an add on device with an IR remote.
