Ben

I wish to thank you for your product and your website which has more information that I expected. I got sucked into the Amazon review train and bought 3 Corro protect units and installed them in my home, mother inlaw and sisters. 5 months later I checked the voltage and found only .03 volts going to my tank which told me the power supply was bad but the green led was bright. I check the other units I installed, same issue, not one of them was over .05 volts. I decided to buy one of your products. As a retire electrical technician, I installed a 2.2Kohm resister between the positive anode wire. The led on your power supply turned red, the corro protec product stayed green with virtually no voltage going to the anode. Your product is sound and I appreciate you being honest about your product vs others. Thanks a million Matt!
