This gun works well and will last a long time if properly lubricated. I've owned one (as a sole proprietor) for over 10 years and use it on timbered houses, barns and dock buildings. I like the presence of fasteners (common 8d-16d and galvanized ring bar 8d-10d). Mine has fallen up to 40 feet onto a large rock (#2) and even concrete many times with no damage. He's been underwater dozens of times. Any time I've had an air leak or supply issue, a good degrease and re-lube will solve my problem. I bought an extra gun (at a super deal with Revain) to put on the shelf because I didn't expect my originals to withstand much more of my abuse, but it lasted another 18 months!
