I had mine installed with our new 18k pool. I've only had it for 7 months, but it has worked as advertised. Now they have the Purelink version which doesn't require an additional box to be installed near your equipment. My pool installer, for some reason, delivered two control boxes and didn't bother to take it when they were done. I have a brand new control box for sale if interested. You'd have to buy the cell and DC cord. The other thing is it integrates nicely with Jandy's Aqualink controllers.
