I finally decided to buy one to help keep my TV relevant. Most of the apps from my 2011 model TV don't work anymore and was limited in functionality. I wish I bought one of these years ago though. Now, reading through previous comments, there is someone who gave 2 stars and complained about being single banded WiFi. This guy doesn't pay attention to what hes looking at. Yes, this is clearly stated that it only uses 2.4GHz band. No, they didn't go backwards in any form with this. With a quick search, and all Roku Expresses, which is what this is, have been single band. And 2.4GHz is fine when only going 1080p for HD.
Now about using it. Setting everything up doesn't take long, around 10-15 minutes. Once you have it set up, it's eay to use to get on Netflix, or Amazon Prime to watch your favorite shows. You can also download some other apps to get some free TV to you flip through another couple hundred channels and complain about there is nothing to watch, because we all know we do that. When watching something, the picture does take a minute to download, buffer, and catch up, so the first little bit may be a bit blurry, but it evens out. There is also the Roku app for your phone, and this adds some ease of use. Instead of using the remote to attempt to hit the sensor on the device, you can connect to the Roku on your phone as long as they are on the same WiFi network.
If you want to stream easier on your TV, or your TV doesn't have the Smart features you want, I would recommend this. If you want 4K video, then you need to look at something else because this doesn't off it. Also, if you really need to use 5GHz WiFi, then also, look elsewhere. Now, I can't compare this to other models, but this works well for what I wanted it for. Would recommend.
