You can get a Steam Link today on Amazon for $15, over 50% off!
I’ve got one hooked up to my living room TV via Ethernet and the convenience factor alone of being able to play PC games from the comfort of my own couch makes the original 30 bucks that I spent on this thing completely worth it.
Personally, I haven’t had any issues with lag or dropouts – and like I said I’ve got the Steam Link hooked up to my TV, while my PC is a floor up in my office.
Get one, for the price of a lunch, and check it out!
