I have used these, even back when I was a kid with fresh water.
I bought one about a year ago, it broke, motor seized after a couple uses... Exchanged it and the second did the same. They are a piece of junk now compared to the old models.
They do a great job, when they work, I just think the quality of build is garbage now. Maybe you can find a better model? If so, let us all know.
