I have a Craftsman corded Electric impact, only really have it for removing the lug-nuts and such on my truck when I work on it. I keep it in my motorhome in case of a flat. I bought it at a swapmeet used, it works really good for what I use it for zips the lugs-nuts off my mh without any hesitation. When I do my springs I'll probably use it to get the tougher bolts off.
