I run my own garage and have x3 air guns that run of a compressor (obviously) and in the x3 years I have been trading I can honestly say that since I have had my snap on gun my compressor and air guns have been used once!!! I would personally not be without mine now.I have x2 bays and x2 guns and they last a good x2-3 days on a full charge at full chat all day long!!! Got to be one of the best investments I have made and I would happily let anyone try mine to see just how good and more importantly powerful they are.
