I just picked up 5 of these for my crew. We have used several different brands in the past, but these are hands down our favorite. The unit is very light weight, which is important when you are using it all day. This gun also has a switch that you can flip with your thumb to change it from single fire to contact fire. The other feature that I really like is that it has a reload inidcator that lets you know when you are out of nails.I will update again when we have used them for a few months, but as of right now I couldn't be happier with all the features that this gun has.
