It is definitely one of the best caulk guns I have had.
Pros: 1. Drip-free: I had absolutely no drip from the start to finish of the cartridge (outdoor silicon). No material wasted. 2. Effortless and easy to control flow rate with the two thrust ratios 3. Solid construction, it will not bend at the junction of the handle lever with body, like the contractor-grade gun I bought at Rona.
Cons: 1. A bit heavier, but it is heavy duty so I don't mind.
Definitely recommend if you are looking for something that will last a long time.
