Performance Tool W54204 Professional 14oz Pistol Grip Grease Gun, Ergonomic and Efficient Lubrication Solution for Industrial and Automotive Applications.

I think their use of the word professional is used loosely, but it works as it should. It is durable and easy to use for the ordinary user. I bought it to grease my travel trailer and vehicles. So I’ve only tested it as a general public user, not as a mechanics shop. Typical grease gun size and works great for me.

Great Grease gun. Great for what I need

I wish you had the option for ZERO stars. I have used grease guns my whole life and have never had one work this poorly. I needed to use marine grease for a specific application but didn't need a full sized gun. I had to force a tube of Lucas Marine grease into the tube with so much force it had me wondering if it was the wrong sized tube. Not only that it would not pump. The threaded tube was poor quality and the threads appeared to be cut with a round rock. No matter what I did it would not pump grease despite seeming to build pressure. Grease squirted out above the handle as well as the plunger opening at the bottom. DO NOT BUY THIS!!! Since it was covered in grease and doubtful I would get a refund it went in the trash. I should have just bought a full sized grease gun despite only having 6 fittings that require the marine grease. Consider yourself warned.

Was hesitant to purchase based off negative reviews, but at thirteen sixty five dollars on 6-13-23 it was worth the gamble. This is the same gun they sell in some of the larger retail auto stores, but at a competitive price.I ran into most issues reviews mentioned. Leaking grease and dry pumps. The leaking grease from the areas circled in my pic was resolved by snugging them down with a slip joint plier (make sure not to cross thread). The coupler then has to be backed off to fit the zerk. This takes some trial and error, but once you hit the sweet spot, simply releasing at an angle will detach from the zerk successfully. Filling the joint/bearing etc is easiest done by keeping the coupler parallel with the fitting. Lower cost guns tend to ooze out if it's not set correctly. Make sure the head of the gun is on really tight to prevent leaking up top. I'd imagine plumber's tape could help threads that won't seal.After filling a couple ball joints, I ran into the dry pump issue after returning to fill some sway bar links. I re-bled the system and dry pumps continued. 20-30 pumps later I felt pressure build and it's been working since.I've been a DIYer for a long time and weigh cost vs quality vs application vs my time. Knowing that less expensive items generally have less quality control and cause more problem solving skills to get things working correctly if they don't work out of the gate or stop working altogether, an item like this that's used every few oil changes is worth my time because it taps into some critical thinking skills if things go wrong. I'm down for that exercise as it expands my ability to problem solve more complex issues down the road.Nonetheless, if use of a grease gun was necessary for my profession, this item would have never been considered. Good luck and keep on greasin'!

Good

I got proper red wheel bearing grease with this product to fill the completely empty void inside the rubber boot and worked great highly recommended. I used this with a needle zeek fitting to insert the grease inside the boot.

This mini grease gun works very well, with good pump pressure and a nozzle that removes from the grease fitting when you twist it to the side and pull -- but it has two flaws: 2) like all of these mini-guns, they are making the grease cylinder so tight that you have to force the grease cartridge into it -- which works until you have to removed the cartridge so you can put in a new one. The manual says to grease the inside of the tube, but this just causes the paper label on the cartridge to swell and makes the problem of removing it even worse. So for those who do not want to spend 15 minutes with a needle-nose pliers ripping out the old cartridge one small piece at a time, you should get a full-size grease gun.2) the air purge screw is has been torqued down by a robot and cannot be turned no matter what you try. But just pumping the handle enough times clears any air bubbles, so it still works.

Works as expected and fits your standard grease tube's. Only thing to really note is DON'T use it in tight spaces. The clip holds really well and doesn't want to release the grease fitting. I'm sure once it's used enough to wear down a little bit it would be perfect.
