Completely dissatisfied. I have several other Aircat tools that I love, but this hammer blew my bucks straight away. It hits really damn hard, but it hits or misses because the trigger feels like you need pliers to pull it back. If something doesn't work for you, all you have to do is tap, tap, tap. I work with heavy equipment all day and struggling with a raised trigger or poor design is a waste of my time and money :-( Sorry Aircat but this one sucks.
