We have been using the Enzo one.drop leakage sensor for a year. We received it through our insurance. We had two major water damages in our house that were not our fault, so we were sensitive to the issue. Luckily!!! Six weeks ago, there was a leak in our water-based fireplace. An emergency sensor had triggered incorrectly, and water, intended for extinguishing and cooling the fireplace, leaked out. Enzo 'responded' and warned us. We were then able to shut off most of the water until the technician fixed the issue—which took four days due to a lack of replacement parts. Without Enzo, we would have had significant damage, and additional costs would have been incurred due to the immense water consumption. Our insurance paid for the damage (repairs) without any issues since we had a valid source in Enzo that confirmed the incident. Thank you, Enzo! 10 out of 10!
