> 3 dayThis things holds on pretty good. I have only had it pop off a few grease fittings. It almost holds on too well. I had a few fittings that would not take grease and I dang near didnt get this thing back off. I would buy again. Only minor issue is it doesnt fit well in a real tight place. I have another grease gun for those fittings.
