Review (1/5): These are crap!
the first week I got the claws I used one and one of the teeth broke out of it. By the end of about a month I have 6 teeth gone in the middle of the claw and it's unusable. I haven't used any of the others yet (1 large and the 2 smaller ones). I do like the strength of the spring, (very strong) but the material the actual claw is made of is very brittle. I would not recommend these to anyone.
