Waterproof, flexible and easy caulking
We bought our new house with little things here and there to do. I haven't used all of one of these yet. It was so easy to use. We had a new tub put in and the plumbers caulking peeled off within a week. I saw this was flexible and waterproof. So far, it is absolutely both and staying on.

It works
It works. Maybe a little pricey for what you get. But it does work.

Super Easy to Use
This was a great purchase. It was super easy to use. I like the fact you can reuse it without it drying out and use it without the need for a separate tube gun. My only warning is if you are working on a bathtub or shower use it on the lowest setting first. It works well but max opening will let out a lot 9f the caulk and make a mess unless you need that much. Otherwise, start on the lowest setting to test a spot first especially if you try to do that without taping first. I will be buying this again when needed.
