Mike

I have been a licensed plumber for the past 33 years in multiple counties in Michigan. I can tell you with certainty that the reviews on Amazon for the highest priced powered anode are cooked. I installed their product and had to replace multiple water tanks at my cost since I recommended their product to my customers. I sent multiple emails to Matt asking for specifics about his product which he responded to every single email within 6 hours so I purchased 6 of them in 2019. Not one tank has failed and the power supplies are still working. This is a rock solid product and I purchase around 108 a month from him.
