Review on Irwin Quick Grip 90 Degree 226410: The Ultimate Tool for Secure and Efficient Clamping by Justin Olson

The work I did wasn't even that hard, just making a frame for paintings. One problem was that there wasn't enough support to hold the parts in place so I added a little more pressure and the screws holding the moving head broke and it was destroyed. I wouldn't recommend this product for anything that requires a strong hold, maybe I just wouldn't recommend a period. I do however have a pair of Irwin quick release grips which are great and will last for years. Sam
