Oh, thought you were fucking around.....
It's a little box you set up to your cable/satellite box, and it lets you watch any televised or recorded tv on your laptop, iPad,phone etc.
Need it so I can watch my Giants out side on the patio tomorrow night.
Had an old version but just bought the newer one.
Can also stream to any tv with my roku streaming stick.
So if I want to pull my 65 out on the patio, I can still get anything on it.
