I've used ATOs very similar to the Avast brand. There were a few differences like the backer and blue hose weren't there, but the clear sensor tube and hose coming out of the top was the same, and an identical magnet was used. There was no logo on the plug in controller box... But I had to replace these units as they were often very inconsistent with the water level. Sometimes these kits would work fine, other times they would over/under fill the sump. They were also a huge pain to get functioning properly after a water change or any other time that they were exposed to air.. Sometimes tilting the unit to release any air trapped would fix it, other times it would not.
I am currently using in tank/in sump ATOs from Autotopoff.com
