I got the 4k stick on prime day £25 my 4k tv wasn't very smart!! Had a droidbox for the smart bit and filled it with loads of apps, gave the stick a try and wouldn't go back to android box now, it is invisible plugged into the 4k HDMI and a spare usb on tv!! impressed with speed and ease of use with downloads iptv the only downside is hdd but seems to be easy to get round that with a few tweaks
