Review on 💧 HM Digital Flow Monitor - High-Performance Water Flow Monitoring Device (Item #: 891144000465) by Aaron Ward

Internal sensor failed after 1193 gallons, less than 2 years. The internal sensor, consisting of an impeller with a magnet that passes the reed switch to count the revolutions of the impeller, no longer works. The magnet doesn't seem to move the reed switch anymore, the other magnet "TEST" turns off the reed switch, so apparently the magnet built into the wheel has lost its magnetism. Wouldn't buy another unit, hopefully HM only sells the impeller with the magnet so I can fix it, otherwise it was a waste of money.
