Holds on as advettised.
Works well and makes it easier to grease the tractor.... only thing to note is it is bigger than I thought it would be and would not fit in one spot.

PROLUBE Has uninvented the grease coupler
This thing is a big hunk of metal and an equally big disappointment. Some how this coupler is worse than the free coupler that comes with your grease gun. I've had the lock n lube before and I lost it, so I took a chance and bought this just to try something new. Worst mistake in my greasing life. It doesn't matter how much access you have or if the zerk is straight or at an angle, this thing will not couple and will not put grease into the fitting. Maybe if you pray enough it will work. Amazon needs to have zero stars as an option.

Didn't last long.
Gave it a 3 because I like the design. Used it on a Fireball grease pump on a 55 gallon drum on a service truck. Easy to use. However it lasted about 3 days of heavy greasing on excavators, earth movers, etc. After close inspection the ball bearings on the locking mechanism appear to be worn so they no longer hold when attached. I really hoped for the best out of this but was let down. Can't recommend this coupler . Might last longer on a hand grease gun.

Neat tool
Easy to use, releases from the grease Zirk easy. A bit larger than most. Works well

Better at being a pepe weight
Doesn't hold on to ANY fittings. Occasionally you can kinda twist it and get it to hold on, but 95% of the time it won't stay. Recessed caterpillar fittings? Not happening, the grease gun fitting is too big to fit, external fittings? Not happening if they aren't the exact perfect 90° zerk these quick connect fittings were made for, it pops right off. Don't waste your money. Just get the lock n lube.
