Does what it claims to do
I like that the clamps take pressure off the fly button (pro tip:  if the button comes out but the hole's not ripped, get an e-clip assortment from your local store).  The device is very light but you don't need to put that much pressure on the cloth to stretch it.  I hang up the pants to dry with a couple of clip-style clothes hangers and the waist is nicely stretched when dry.  I have read some reviews that say the waist will shrink again if dried in a clothes dryer, but I have not tested this.
