The port where the tubing connects to the switch is not secure and can easily fall off with the slightest pull which would trigger the top off water pump to stay on and cause a flood. The sensor tube also needs an outer sleeve of pipe (perhaps 1-1/2" pvc) to keep it from swinging around in a water body that has any amount of turbulence.
If you don't have any snails or plant roots in your water body, you would be better off with a float switch type of auto top off.

great product but it's my first ato device. i do not any anything to compare it to as of yet but is definitely one of the most expensive ato devices out there

Simple, yet reliable. I've had it working in my sump now for several months and it's been working flawlessly. Operates by a drop in the water pressure in a tube you mount vertically in the water. Would have appreciated a little more detail in the description before I bought, otherwise, satisfied with this purchase.
