Review: Worked well and gave proper sensor readings. - Perfect for what I needed. I was doing a project where I needed to calibrate a hall effect sensor. These were a nice stand in. Worked well, would recommend. Did not use it for a grow farm.
Review: Total junk - I can not even begin to explain what a poece of junk these are, i just dropped one, it shattered, i teflon taped the hell out of one,still felt loose in 1/2 pvc, taped it like crazy even more, and it had a pin point hole in the plastic , finally wrapped up with half a role of teflon tape my first gallon through it 1700 pulses, next one 800ish pulses, i tried it al one flaow rate not adjusting itnat all oi got 900 pulses, then did the exact same thing and got 1500pulses. I dont know why you would have a flow sensor like this . Tital junk, i asked grok about ut , it said I ts junk.

### ⭐⭐⭐⭐⭐ I used one of the two to repair my tankless water heater
*by I***! on December 5, 2024*

Really nice addition when replacing a water sensor in my tankless water heater. The old one was all black and you couldn't see what was going on inside the device. This one is clear and you can see the water moving and the device inside spinning. Wonderful now I can tell visually if it is working! The wires were too short for me so I soldered on some extra wire and covered the joint with heat srinkable tubing.
