Go buy one, you'll see. I own other Milwaukee tools, at the time I bought mine, they had more pressure than most of their competitors. I've owned Lincolns and you couldn't give me one today, heavy, cumbersome, no power, constantly changing batteries, blah, blah, blah. The Milwaukee 12V is compact, light, puts out some pressure, and averages 6 tubes of grease per small 12V battery. I just swap it out once a week. Year before last I was on a Wirtgen W2100 all summer, I greased 72 grease fittings daily on it, I used the hell out of it and NEVER HAD AN ISSUE. You wanted an opinion, now you got one.
