Strike 'n Swipe

Has anyone tried these things? http://www.strikenswipeonline.com/

I got a pack and went to the range today to try them out. The package says they can detect even a 1" putt so they should be fairly sensitive, but I could barely see any marks. I don't have the fastest swing in the world, but I would think it would still be hard enough of an impact to make a mark.

The only marks that were really evident were the places where the plastic ripped.

Did I get a bad batch or is this just a crappy product?

I haven't used them but it may be that they are less sensitive when it's cooler.
