So far so good. We use netflix quite a bit and it's worked great. I would guess you would need at least average internet speed for it work well all the time. I have never had an issue with it. If you have an iphone, it's pretty cool. You can mirror video, music, and pictures to your tv and then stereo (if you have one hooked up). We use it to look at pictures quite a bit. It's also pretty cool for video podcasts that can stream from your phone of computer. Endless options of things to get off iTunes when it comes to podcasts. I'd say that youtube is a bit slow to load at times but most of the time it's pretty solid. There is a lot more on there that I haven't gotten to but I'd say that it's a pretty cool device and at only $99, a great value.
