It worked on the front U-Joint of my 1990 F-150. It wouldn't clip on, because it was still at an angle, but with a little elbow grease---it worked like a chaaaam!

Seems to be OK. I have not used it. I am giving it 5 stars because it appears OK but I can't guarantee it's utility. I saw some on the local market for $85 (not the same brand) but at this price plus the cost of freight forwarding to Panama the country and I can't complain about its appearance.

Slim design fits tight spaces, decent attachments. The mekanism that grabs the grease fitting will break if used on a clogged fitting, works great otherwise. I ordered a 2nd one of these to replace the one that broke. Use something else for clogs.

Original coupler from my 20 year old made in India Harbor Freight grease gun measured in at .588”, this one measured in at .537”. My old couplers teeth were worn out and the inner bushing was broken. Making greasing impossible. This new coupler definitely is smaller in diameter. The jaw extend out, and a little pressure it slips on the fitting. I just rebuilt two drive shafts, and greasing the U-joints was a breeze. Definitely recommend, saved me time, frustration, and a cleaner grease job.

Garbage. I could never get the gun to work. I bought a smaller one and it works great. The product seems well built, along with the fittings. Maybe I got a bad one. I couldn’t return it since I took a long time to use it.

Great product! Easily latches on to the zerk fitting and releases with a push of the lever. No more falling off or excess yanking on the grease gun nozzle to release. I know it seems like a ridiculously stupid thing, but this item makes easy work of lubing my Jeep. You do need straight access to put this on. It will not fit the zerk fitting if you try to put it on at an angle. I'm now looking for a short stubby one that with a right angle that I can use, but this one works great in a straight-line.

I previously utilized a lock n lube and bought this as a replacement. On the positive it is cheaper. It has a long enough nose to connect to most recessed zerks. There are no leaks even at high pressures. Device is pretty easy to connect. The problem is that if a zerk is plugged and the pressure gets high, this device has no way to release the coupler! If you are successful in releasing you will take a grease bath from the high pressure grease that will fly everywhere upon release. This is a major opportunity for improvement in this product. With a release mechanism that is easy both under pressure and not, this would be a 5 star device. Without it, only 3 stars because plugged zerks for me happen to be fairly common working older equipment.
