Gotta tell ya Scottyballs, this thing works great so far,on my 2nd filled cart. Only punched a pinhole or 2 in the center. Maybe I'l lucky that it sits at the right spot in the cart but it's pretty amazing.
What's killing me is inserting it and trying to get it right without it falling in and me having to fish it out.
I only have 1 done, I don't have a lot of carts and don't want to use up the caps as I use them to carry extra carts around.
If anyone knows where to find some of this stuff that you could use other than the caps, that would be great.
