So far I don't really have any issues with this device. Works great, looks great, feels great. It's honestly a nice step up from the stick and the current fire tv.
Though a few things that bother me would be that it doesn't have an aux jack (3 generations in and we still don't have that). The ethernet port is not actually on the device, it just connects via an adapter. Even though it shows up as a fire tv it has echo options, but it doesn't allow you to add it to a multiroom music group (which would be perfect), and finally, I require a case for it as I don't care for the glossy finish, dust/fingerprint magnet xP
Oh, and I can't seem to get it to understand the inputs on my tv, and I don't get what inputs it thinks exist but none of the options say "hdmi 1-3"....so I suggest you guys fix that
But other than that, I have little to no problems here and I actually really enjoy the device. Just needs some minor upgrades/updates and all should be well.
