Auto top off

[superbeast1965]

I am looking to get an auto top off system. I am considering this one by JBJ unless someone has any bad press to give this system. Any thoughts?

They are pretty good.It's nice to have 2 switchs,in case one sticks the other will cut it off.

I use a double switch in my sump like dave mentioned, from these guys:

Haven't had an issue with any of their products after years of use.
