In general, the product is simple and all the caps are the same size and shape. However, the product is a bit expensive. I ordered 25 capsules for about $25. It's a piece of rubber that shouldn't cost more than $15. Includes tweezers for removing caps. I have a problem. My cleats are 17mm 10 points. And the hats are big. I tested the caps on a 17mm hex and they fit. Since they don't work for me, I will be returning the product.
