Cosmostar Mixing and Dispensing Gun, Impression Mixing Dispensing AB Gun Ratio 1:1/1:2 for 50ml, Compatible with 3M Adhesive 04747 cartridges, CosmoMix Mixing Epoxy Cartridge Dispenser Gun

Excellent tool, works well with epoxy cartridges that I use. Seems to be well made. Decent value.

This is EXACTLY what I needed. Was stuck in a situation where I needed a little Panel Bond, not a lot. By chance noticed this gun and thought for the price, why not, and ordered a 50ml tube of 3M Panel Bond 38315. It's a match made in heaven.The gun itself is actually FAR more sturdy than I expected. And everything operated smoothly and as expected. My one (minor) critique would be that the plunger teeth could have been a bit more fine. I find myself at odd points having to do an extra long pull to get to the next tooth.Won't be using it a whole lot but I have no doubts as to it holding up. Really happy with this purchase.

Product works very good for what it's designed to do. Great product, quality, and price point. Definitely better than the $150 3M equivalent.

Works great simple inexpensive and easy to use

This is great for the 2 part adhesives such as 3M 4240

Compatibility with smaller cartridges. Wasn't clear to me about size.

Works like a champ at a fraction of the cost. Saves money by being so accurate and not wasting product $$.

Some of these types of dispensers run in the 100's dollars. Great price and a quality dispensing tool. FYI to all you newbies out there (including me!): This is called a 50mL dispensing gun. It only dispensers 50mL cartridges. You must also use 50mL dispensing mixing tube. They usually sell in multiple packages. Available on Amazon. Use them once, discard, put the cap back on the adhesive, and can use a new one. The gun comes with NO instructions. But, if you look at YouTube, you will see how to load it and use it properly. This is really a nice gun for the price.
