Review on ZAOJIAO Auto Top Off Solution Adjustable Mounting by Lindsay Siebert

Not well thought out. I have a fairly standard sized tank and it won't fit because the bolts are too long. I tried emailing the sender to see if there are shorter screws to make it more functional but got no response. My return period has now expired. I will only spend a bit more for an ATO with electronic eyes for safety reasons. This will flood if not properly secured. It may work for you but not for me.
