I have found some on carts and then used them for a round or two before I left them on a cart myself !

I just toss it on the ground when I'm hitting and usually chip and putt with it in my chops (which has alot to do with why I don't like big ring sizes lol) but if I was to get something I think I would do this Get a Grip. I definitely wouldn't want the ones where you lay it in there because it would be gone if the cart moved before I got back.

As to the original post that I just realized I never acknowledged - the stuff looks nice, but I already have cutters, lighter and trays so I can't see buying another just because it's green. Maybe if I was just starting out and needed a set, or as a gift idea and notice it came out right before Father's Day.....
