Their website has no customer service department. Only a toll number and an address.
A difficult to find website instruction says to hold the lever forward if it slips off. Doesn't work with the pressures involved. Plus, their website brag is that it is a one hand operation. Not so if the other hand has to hold the lever.
Now the coupler is supposed to come with extra jaws and a seal for a 25% greater price according to the website.
I'm going to try the toll number to see what happens.
Edit update: Just got off the phone with customer service (I believe it was the owner.) We had a very informative conversation that speaks volumes about the integrity and genuineness of the company. I am very pleased with the results of the conversation and would rate the company as a whole as 5+ stars. I urge anybody that wants this product to feel confident that it will work and, in the rare case of a problem, it will be resolved.
Considering that my car is very cramped (VW Golf R) and that even if the fittings were in an easily accessible area it would probably still be a pain to keep the tool on the fitting...especially at the right angle. In addition the grease can get pricey so I wouldn’t want to spill any for no reason.
As it turns out it isn’t hard to get to the fittings, but keeping linear pressure on them would be a real pain - especially without a lift. This little bad boy makes things amazingly simple, heck for some of the fittings I don’t need to remove any parts - just need to have enough room for the part to fit and you’re golden.
Line the coupler up, press down and lock it onto the fitting. Then you can leave it alone and just operate your gun. It was effective to the point that I wasn’t sure if grease was making its way through until it came out of the bushing. I’ve never done it the old fashioned way, but this seems like it’s worth at least 5-10 min per fitting (for a newbie mechanic working in their garage). That alone justifies the price to me.
I sent this to a couple friends I know - a mechanic and a friend that grew up on a farm (and uses the farm shop to do their work). They both instantly spent the $30 and bought it. To me that validates the price/value.
Combined with the fact that it works as advertised I’d say that this is a great buy. Don’t regret almost doubling the cost of my grease gun for it!
Update: Having put this into service I have to agree with myself---great tool! :) In fact its so good I've changed a few Zerks to accommodate its longer length, previously I was using a Lincoln-variant that would swivel for tight areas of which I had a few. Changing those Zerks to 90 and 45 degree fittings gives me full and complete access now. Being able to clip it in place gives me two free hands to power the grease fill, not having to hold the filler in place.
It does leave a bit of grease on the end but its no worse than another other filling attachment. Overall I highly recommend this without reservation!

There were two problems with it:
1) this coupler is larger than a standard grease coupler and Zerk fittings tend to be in some tight spaces and getting it to lock on properly was a hassle on most of my zerks (more hassle than holding a regular coupler in place for 5-10 pumps)
2) once locked on, it worked well at first but after greasing ~25 zerks and in a few weeks, it's leaking in applications where it didn't leak originally unless I really push it into place, which in some cases is impossible due to zerk fitting locations.
If you usually work on larger machinery with relatively unobstructed access to zerks then this coupler may do really well, but unfortunately it didn't work well with zerks in tight spaces
Bought a different style first that was too big.
On this one the outer case (sleeve) pulls back to open the jaws so it fits in a smaller space. I put it on a battery powered (Milwaukee) grease gun and it held the pressure and still releases just fine. Very satisfied.
Btw, it comes with spare "jaws" and parts so I imagine it'll last a long time.
I cant even pick up a regular tip grease gun anymore without walking back to the shop for the dewalt with lockNlube.
Only issue ive had is pto shafts with covers on. Solutions inculde buy the extended lockNlube which i likely will one day or as ive done heat a razor blade up and melt/cut the cover hole slightly larger, it doesnt need to be much bigger.
Buy it. You will never regret it. It works amazing
