you get what you pay for
What do you expect for $20?  It's a cheap strap system held together by typical key-chain loops.  Still useful enough as long as you don't have ridiculous amounts of pull against it.  My only issue with this product that I will not accept is due to the price is their claim that it fits any size bed.  If you have a king size bed, and extend every strap as far as it can go, (there are no stops to keep the straps from being pulled out completely), the actual restraints will peek out of each side of the bed with about 3 inches of slack.
