The Original, Made in The USA by LockNLube! Cleans and flushes Out Old Dried Grease from Fittings, pins, shafts, bushings, and Joints. Uses penetrating Fluid and Hydraulic Pressure.

Worked like a charm. Took a few good wacks with a large hammer. Oil shot through the sleeve of the bolt and cleaned it out. Perfect!

I am NOT a skilled mechanic. I am 71 years old and what little I know about mechanics I figured out on my own or got help from buddies (in the old days) or found a solution on Google or You Tube (now a days).This was my problem: I recently bought a Texas Pride 16,000 GVWR 22' + 2' lowboy trailer with tandem axles and drive over fenders. It was time to add a little grease to 6 fittings. Everything went well on the first 5 fittings. I could not pump any grease into the last fitting (of course).I have been tinkering with stuff for a long time and I know how to use a grease gun. But I have never had a fitting to not accept grease. I removed the fitting (remember this is a brand new trailer) and cleaned it up. The fitting was deformed. That made me wonder if this spot had been greased at the factory. (Turns out it had not.). Anyway, simple fix. Off to the auto parts store to purchase my zerks.Got home, installed a new fitting and NOTHING. So I removed the fitting and put in another new one. Still nothing. I put a fitting on the grease gun and it took grease (as long as the fitting wasn't screwed into the trailer. So grease was definitely able to pass from the grease gun through the zerk.Time to check out You Tube. I found a video about the Original Grease Buster. I read reviews, compare it to knock-offs and thought this thing couldn't possible work in my situation.Well, I didn't have anything to lose thanks to Amazon's free returns. I received the Original Grease Buster the next day. I followed the instructions in the video and on the packaging. Less than 15 minutes after I received the Original Grease Buster the axle hanger was fully greased and the trailer was ready for the road.Final thoughts If you work on anything that has grease fittings you need to buy an Original Grease Buster and drop it in your toolbox now because it might not take you 71 years to run up against a fitting that won't take the grease. I know the dang thing is pricey. But IT WORKS.

Have used these for years just needed a new one. Beats the hell out of taking the zerk off and trying to put a new one on. They hold up to abuse well and work great.

Had mixed results based on different circumstances. If your grease joints are seized solid this won’t perform a miracle but if it’s just gummed up this will work just fine. Build quality is very nice. Great tool to have on hand. If I had this before the one bad joint it didn’t work on would have been addressed years ago and been fine. This will keep you ahead of the game

All in all this thing works pretty good, it's kinda messy to store i wish they include a better bag to store this oily thing. Also yall need to make and adapter to go to sds hammer drills. The air hammer is nice but no one makes a cordless air hammer. I ended up making my own. Sds is the way to go.

Give it time and it will work.

It looks like a good made tool. I filled the cylinder with penetrating fluid by instructions and it leaked out fast. The grease zerk end fell a part after second use. I was really disappointed price wise and performance of this item. Worthless tool!

So I bought this a while ago and honestly haven’t had to use it. Finally got to use it the other day On a grease CERT That just wouldn’t take grease. Just putting a couple of taps on the end, clean the grease right out. I would highly recommend it
