Slippery Pete Mini Pistol Grip Grease Gun. Heavy Duty Design for 3oz Cartridges. 12 inch Flexible Hose and 5 inch Rigid Extension Pipe

I like that the plunger rod of this 3 oz. gun can be pulled back & locked in place (like the old ones were, and some still are). I like that both the front and rear heads unscrew and can be removed which can be helpful in removing an empty cartridge. I like that the zerk fitting can be opened slightly (be careful not to unscrew it too far as the tiny grippers can fall out; don't ask how I know this), then retightened onto the zerk being lubed. This eliminates grease from squirting outside the fitting rather than into it.

Worked great with no issues on loading cartridge

Nice little grease gun with plenty of grease for average jobs like suspension on light duty vehicles

Instruction manual isn't super clear for a total newbie. Ended up losing a tube of grease trying to figure it out. Works well now that I've figured it out.

Best mini grease gun I own.

Very easy to load grease gun. This can be a challenge on inferior products. This one is very well made.

[Original 3 star review, downgraded to 1 star after more experience - see edit at bottom] Seems like a decent inexpensive grease gun. It's not the best thing, but it's an okay thing. When loading it, you have to be very careful when loading because the handle can pop out of its notch and send grease exploding out of the tube. You don't have to bump the handle. You just have to bump the grease gun lightly for this to happen. It wouldn't release the zerk fitting. I had to move it all the way to one side so it was at an angle, then pry it off with two screwdrivers, one on either side. THEN it came off. I don't regret buying it because it does the job and is inexpensive. It's okay for the occasional user as long as you keep two flat head screwdrivers handy when using it. If you need a grease gun for frequent use, move on. [EDIT] Today (Jan 9, 2020) I finally got so fed up with this thing that I threw it in the trash. Once AGAIN while trying to load up new tube, the plunger popped out of its "locking position" and sent grease everywhere. The first time this happened I chalked it up to user error. But it has happened on nearly every reload. The thing is so poorly locked that almost any little bump knocks it out, then the spring does the rest. It is extremely difficult to hold this thing steady enough to successfully reload it. I have spent more on popped grease tubes than I did on the grease gun. And I'm also tired of having to pry it off of every zerk fitting. I am done with this thing.

I learned a long time ago as a School Psychologist that many Teachers did not know or understand how to give explicit instructions to their students toward helping them succeed better in the classroom and prevent needless failures. Let me tell you, reading and executing the instructions on how to load and activate this Grease Gun is a lesson in how to waste 1/3 to 2/3 of the grease (which was expelled on my garage floor). That just about doubled my purchase price and aggravated the heck out of an honest customer. Good, understandable, foolproof instructions are very difficult, but not impossible to write. SP Mini Grease Gun could and should do a MUCH better job, but they apparently don't care enough to put someone in that job who knows how to write in the English language well enough for the average novice to prevent the disaster that I experienced.
