Astro Pneumatic Tool 101 Mini Grease Gun

Works great. It is a hand pack but that's to be expected from such a small gun. Works great on all my machines and impact guns.

I have been using the "other" types of bar greasers for decades and they were fine. BUT this grease gun is far, far, far superior to "those".Why? It has a lot more power and makes greasing the nose super easy. One easy-to-apply thumb pump and you are done. PLUS, you can fill it with grease for a BUCK+- and use the grease YOU want to use. In my case, I have 30 gallon barrels of grease and the fill cost is almost pennies.This grease gun works amazingly good. Highly Recommended.

I’ve used it several times on my 24 inch echo bar works well I enjoy the fact it lets me choose what grease I want to use.

A good little mini grease gun that works fine now that the tip is drilled out. (yes the top is blue because I painted it to tell it apart from others on the workbench). After I filled it with Park Bicycle Grease using an old spoon, I could not get any grease out, no matter how hard I tried. Finally looked at the tip and the hole, if there even was a hole, was too small to let any grease out. The smallest bit I have is 1/16" so I drilled the tip out with it. Just took a few seconds, and now it works just fine. If I had had a smaller wire guage bit I would have used it, but 1/16" is fine and lays a nice bead of grease. Should come from the manufacturer with a better tip.

First I bought a tube of bike lube (Finish Line) with ptfe (e.g. teflon). It works, is easy to squeeze, and a bit messy. But a 16 oz jar of grease and this grease gun is a much better deal and a more lasting solution. I'll still take the 2 oz tube of bike lube when I travel with a disassembled bike. (Whatever happened to 35mm film canisters?!)My grease gun arrived with a perfectly fine pinpoint hole in the nozzle, ready to go.True, the instructions are on the side of the grease gun. 1) I unscrewed the top. 2) I used a piece of plastic coated cardboard from my trash can as a paddle (cut to just fit inside the tube,) and started paddling in my grease. (True, the picture shows a finger.) 3a) Once I had crammed in as much grease as I could easily fit, I put the lid on firmly, shoved the disk inside the bottom toward the top with a screwdriver, and then took the lid back off. (True, this was an extra step not pictured on the can.) 3b) Now I took the cartridge and sharply hit the bottom of it downward onto my other hand. What do you know, the grease slid in, allowing me to again fill the cartridge. (True, the pictures don't show filling the cartridge more after the tapping.) Filling it twice was good enough. 4) I screwed the top on tightly (by hand firmly) so the grease wouldn't leak through the threads, pressed up again through the hole in the bottom with the screwdriver, more firmly this time. (True, the instructions show the cap on, while the previous picture shows it off.) 5) I began to pump the spring-loaded plunger (with the tip pointed toward my open can of grease.) A satisfying, but highly controlled thread of grease emerged from the pinpoint tip. (True, there is no fifth picture on the can.)I'm actually using Finish Line Ceramic Grease, which has both ceramic and fluoropolymer (ptfe, teflon, etc) additives. A 16 oz tub ends up cheaper than multiple tubes of grease, even including this grease gun.But still, a ziploc baggy with a hole cut in the corner, and automotive grease would be cheaper, so this is more or less a little luxury for a guy who buys his fancy bikes off Craigslist.... To each his own!

These are nice to have. Have several with different greases in them and it puts it right where you need it. Also use one to grease up air tools that have the needle valves in them. Work just as they should.

Great Product.

Much easier to use than the plastic ones. It's very well made and built to last, I'm pleased!
