| After struggling with many different types of air operated grease guns, I decided to try the battery operated one. What a difference!! I am extremely pleased with the 14.4 volt gun. It doesn't lack power and the batteries seem to last quite a long time. I am a mobile oil change service, so it gets used a lot every day. One of the biggest problems I had with the air guns was losing prime halfway through a tube of grease. Not so with this one, in fact I have already run about 20 tubes through it and it hasn't faltered yet. I would definitely recommend this gun to anyone looking for one. THANKS , CHRIS |
