Review on Ez Shim Heavy Duty Shims Count: Durable and Reliable Shim Solution by Robert Berio

Not sure if they could be better. This is a definite improvement over the already excellent composite wood and plastic pads I usually use. I have used them to level a very heavy (1800lb) safe on concrete and they worked as I had hoped. That means it snaps in easily and snaps flush without being compressed by weight. Highly recommended! I really can't understand some one star reviews. This product is really excellent for the purpose it was designed for so I suspect that people who find fault with it will try to abuse or abuse it. Update: Two years later, my safe is still shaking. - loose and the seals are not compressed at all. I daresay these pads will last indefinitely.
