Joe, I have 40 of them that I have been using since 2002. None broken or even chipped. If you use them in a leather shell box holder, wet the corners of the leather and jam one of the caddys in, I also shoved some shim shingles in around the corners and let it dry in the sun. Worked fine ever since. Good luck. Harv
Prices on the Trap Happens site are about the same for the boxes as the Ebay seller but the shipping charges on the boxes are just about half as high. Trap Happens looks like the place the go.......Thanks Matt.
I have about 80 and like them. Had them for 4 years and none broken yet.
I use 5 gallon pails to hold reloads (500-525) and do not box practice shells. The 4 sided Shell Caddy box makes it easy to "box" shells between rounds. Just slip the 5 sided box over it; flip the assembly over; place in pouch and remove 4 sided box.
500-525 empty hulls fit in a 5 gallon pail.
I still use cardboard boxes and flats for ATA shoots.
