Has anyone tried Style Snaps (as seen on tv)?

In case you haven't seen them, they are a way to hem your pants and change the length based on your shoes. I'm wondering if they really work or not.

Thanks.

Ooh, I've not seen them, but how neat!

Looks pretty neat. I'd love to have them work! Expensive though! I wonder if you can get them somewhere else without all the shipping charges.

If you wait a bit, they'll most likely end up in BBB or Walgreens in the 'As Seen On Tv aisle, which is a very fun aisle. They do look interesting but I wonder how well they'll stick after washing? Hopefully like a Mabel's label :)
