I drive old used cars and those from the rust prone areas of the country can have a lot of fun disassembling them. I don't use it often because it's so big and powerful, but sometimes I need it and there's no substitute. I bought this after seeing Eric the Car Guy use a Big Nasty (AP rival hammer) on a rusted Subaru rear tie rod bolt and it was more than worth it. Whoever compared it to a gun was right. I use some big 200 ton pistons at work, but that's insane power to hold in your hands. I try to keep my hand on the barrel at all times to control it when using the hammer club, otherwise it can go anywhere and destroy anything in its path. Treat this thing with respect - I'm sure it can break every bone in my hand. in a split second when he leaves me in a confined space.
