I was apprehensive about buying this till I talked with a trusted friend who had one.  She said it was great and could be transferred from TV to TV in the house. (must stay within com distance of your Wi-Fi device).The Roku 3, which is the model I purchased, requires HMDI cable to the TV and Wi-Fi connection OR Ethernet (Cat 5) cable to the Internet.Once connected there were just a few very easy on-screen prompts to connect and sign-on to the Roku.ONE VERY IMPORTANT CONNECTION STEP: In my research of the Roku I kept seeing the same step emphasized to connect the Roku.  You're TV should have several &#34;source&#34; connections (where the source program inters the TV).  The remote control should have a &#34;source&#34; selector.  If you don't go to the correct &#34;source&#34; input you will not see the Roku input.  READ AND FOLLOW THE INSTRUCTIONS THAT COME WITH THE ROKU.  The included instructions for mine were very easy to understand.Most programming received through the Roku is subscription based, or &#34;Pay Per View&#34;, with a couple of exceptions, like UTube.  I am a NetFlix subscriber so I just added &#34;ON-DEMAND&#34; services for a few extra dollars a month.Roku 3 has a very small remote control.  It's very easy, comes with ear buds to plug into the remote for private listening, and the remote works on Radio Frequencies instead of Infra-Red to communicate with the Roku.  This means that the remote does NOT have to have an unobstructed line-of-sight to the Roku.It sounds like, from what I've read, some of the earlier models are very good also.  So, if you are counting penny's you might consider them.  Some have different connection requirements/abilities.BOTTOM LINE: I would recommend this device to my friends.
