I'm tired of the cheap caulking guns from your favorite big box store so I switched to a professional caulking gun. Since I've just started using it, I can't comment on long-term use. Pros: 1- Sturdy construction, should last a long time. 2- Precise control and less effort. 3- No leaks around the piston like cheap pistols. Cons: Not yet, as I said, I've just started using it. I'm just starting a project that will require a lot of caulking and sealing and will update my review if there are any issues. I don't expect anything negative as it's built really well.
