So far no issues. Am enjoying it. Still getting used to os. Starting to like it so much I went to Best Buy and got Apple TV to replace Roku that is dying out. As posted earlier am planning on getting Iphone later in year when get some things paid off. Probably 6s Plus.
Glad to hear it is working out for you, and congrats on the Apple TV. I have both an Apple TV and a Roku, as well. While I still tend to prefer the Roku, largely because of Amazon and other apps being available, the ATV has some nice features. One "trick", if you use Amazon, is that once you use AirPlay to mirror the video to your ATV, on your iPad (or iPhone) it shows what actors are on screen, as well as sometimes includes notes about particularly scenes.
The other think I highly recommend on the Apple TV is to set your screen saver to the Aerial screensaver. Some amazing flyovers of various cities and landscapes.
