Query: Works as good as more expensive closers!

Length:: 0:07 MinsPerfect for the door we have between shops; one heated/air conditioned, and one not! Somebody was always bursting through the door and leaving it wide open costing us lots of $$$ in wasted heating & a/c. Now, it will open very easily, and close properly. It will more than pay for itself! Very good quality for the price!!!!
