It's better than a pneumatic

I've been using this for over a year now and it works great and has plenty of power for automotive use. It can easily pull off lug nuts on 1tons which are close to 200ft/lbs. it's lighter than my pneumatic impacts and just as powerful. Much more convenient with no hose to get tangled.
