I have the milwaukee 18v fuel with hard case... it's OK. I mainly got it because I was switching my cordless tools from dewalt after a bunch of them got stolen
I still like my alemite but the batteries are finally giving up so on to newer and better
Have used it quite a few times and it seems to work good... plenty of pressure fairly quick and the tube cylinder makes it easy to thread unlike some guns where if you're in an odd position trying to change tubes it can take a while... I remember a there were a few things I didn't like about it... but can't recall them right at this moment...
