Our situation. Our home has well water and chews through anode rods every 4 months. In the month of October 2020, we found corro protect on Amazon and purchased it. The odor was gone 2 days later and we were very pleased. I will never forget the time, on December 24th my husband noticed the power supply was flikering of and on. We called the seller water connection who sold the item to us on Amazon. We were told to contact corro protec. We called their 800 number and were told it was out of warranty for a return but they sent us another led box. It faild 2 weeks later with no light this time. I asked for a money back and was told it was beyond the return window. My husband said we are going back to the anode rod.
I contacted water tank tec on Amazon and after several emails, decided to buy this companies product which was a lot less than the corro protect product. I can say as of this review April 24. 2021 I and hubby are very pleased.
I will mention 2 things, great customer service by water tank tec, terible with corro protect and amazon. We tried to leave a review on amazon which is the site we purchased water tank tec from but it was never posted.
