I bought this new at Best Buy about 4 months ago and used it maybe 3 times since then. You can connect it wired or wireless to your internet and then you can watch Youtube or Netflix. Theres also a Samsung app store where you can download any other apps for movies, TV shows, ect
This only can be used on tvs with HDMI. Perfect condition no scratchesor marks at all as I have had it put away in a closet
