I know this is not the right forum for this but I can answer your question with a resounding yes. I run a fleet maintenance shop for a large utility company and we have three of them in use on a daily basis. I have two techs that are in the field and they each have one and I have one for my four shop techs. When I tell you they get used alot I mean several times a day. We service the hydraulic manlifts and pole setters we see each one on a quarterly basis and they hve 8 to 10 grease fitings each. The only componenet we have to replace are the batteries which last a year or two as far as the gun itself I do not think I have had to replace that ever and we have one gun that is at least 7 years old. Hope this helps.
