Was so excited to get this after seeing it in use. I bought it for a small project I was doing. Unfortunately, after opening the package and going to my workbench, the swivel head fell to the ground. I checked it out and no visible problems so I was able to click it back. Every time I held it a certain way and after releasing the clamp, the head would detach and fly somewhere. I expected more from Kreg, I like their instruments but this is very disappointing. I would return it but it will be too expensive to be worth it. Needless to say, I have completed my project. I hope it might be a bad batch. I'm sure I can change it, but I hate doing it.
