Review on Superior SolidWork Professional Hand Caulking Gun with Highest 24:1 Thrust Ratio - Perfect for 10oz Sealant and Adhesive Cartridges and Tubes - Drip-free Silicone Gun in Blue by Adam Huper

Pros: It is durable and well packaged in a sturdy box. The puncture needle is thick and does not bend easily, if at all, and is well positioned. Cons: I don't know if I just hit it, but it makes an annoying clicking noise every time I squeeze the handle to release the sealant. . The body turns with difficulty; It is very hard. You must press the rear lever to stop the sealant flow; I thought it would stop automatically, but it doesn't; If you don't push the rear lever down (sometimes hard to do), it will keep flowing out. And sometimes it keeps flowing even after you push the lever. You have to follow that.
