Review on Edward Tools Drip Free Smooth Rod 10 oz Caulk Gun with 15:1 Thrust Ratio - Ideal for Industrial and DIY Home Use - All Steel Construction for Dap, Sealants, and More! by Drew Poulin

This is a standard cheap caulking gun; I didn't expect much. I used a very viscous glue cartridge. It took a lot of effort, but the job was done. It was VERY hard to let go of the trigger. When removing the cartridge I saw that the piston rod was slightly bent. I didn't really think about it at the time. The second time I used it, I noticed that nothing came out. With more pressure, the rivets on the handle gave way and detached from the tube mount. Turns out he was just tied up, not tied up. I have already returned it. It's not worth the cheap price. Just pay a dollar more and get better quality.
