What can i say. Amazing! Well built and have some serious clamping power, they dont gradually slide loose and the reversing jaws are very handy. A great purchase

### ⭐⭐⭐⭐⭐ Easy to apply pressure and just as easy to release
*by B***H on 8 April 2016*

As I get older (now over 70) I find it difficult to tighten things up as strongly as i used to and need all the help I can get. This Irwin Quick-Grip really works for me. Very easy to bring the jaws together and apply lots of pressure and just as easy to release after use. Well made so should last a long time. I only purchased one just in case I did not like it but will buy another to make a pair.
