C-Level Top Off controller

Has anyone used the C-Level Mach III controller for an aquarium top off system.
Ive been using a simple float valve gravity fed, but ive had several near failures. I am going on a long buisness trip, and the person taking care of my tank needs something failsafe they can just put water in and this looks good from the site, but i cant find any reviews or anything.

or does anyone know something similar that they can recommend

 

I use the Ultra Precise ATO found here but I see that particular model is out of stock, they have many other choices though:

They are also a 3Reef Sponsor and have a Sponsors Forum here to answer all your questions.

Nice thing about the UPLC is it comes with a 3 roller persitaltic pump, same as used in their popular Liter Meter, and is bulletproof. Also has a back up float switch for a backup shutoff in case of failure and like the one you linked to has adjustable run times.
