Like others I've generally used lower quality/ cost caulk guns since they take such a beating (in the trades), but I have to say, this product stands head and shoulders above most if not all and is very reasonably priced $12. No reason to use anything other. Sure you can cheaper ones for 1/2 the price, but seriously, once you use this, you won't want to go back.
