ALMOST bought the Irwin, glad I waited for the Dewalt, for the handle alone. With the squeeze part on top, you can use your foot and step on it rather than have to squeeze by hand like the Irwin.
Nice. My first thought is on release an instant drop . Dewalt thought about this so the slow release is good. This is also a problem with ceiling props. You need to hold the prop up when releasing pressure otherwise the whole prop falls and could fall on something.
