The sensor is a mini optical infrared sensor for extremely precise regulation.It checks/fills frequently,the water level max to min is no more than 5mm,meaning a lesser amount of water fluction;where is suitable for small tanks.It has a magnetic suction cup,so it can be easily and safely mounted within the fish tank.Safety for using in marine or fresh water,built in alarm

Sleek & Small But Does Not Perform In 54 or 127 Gal Tanks
I really wanted to love this top-off system. It is very small and sleek but does not perform at all. We have a 127 gal reef tank (we are not new to this!) and hoped to use this for our auto refill. We also have a 54 gal reef tank and were searching for top-off systems for both. Everything connected smoothly and easily, but all the unit did was flash the lights and beep incessantly. No amount of changing location, tubing height, tubing distance, depth, pumps, monitor, etc...NOTHING made this perform as it should. In EITHER tank. We tested this thing for hours and were never able to successfully have it fill anything. Very disappointed.

solid 3 so far but I'll give it 4 based what it offers for the cost. I posted a video review.

Probably works.
Probably works well if they could send it with all the parts . After two returns I gave up.
