Rating: ★★★★☆ Reviewer: Travis

"Easy install and seems to be a better long-term solution for tank integrity. Surprisingly the factory anode was already heavily corroded in only 3 years. I had to cut some parts and dig foam out with a screwdriver, but the installation was not difficult. A solid purchase so far."

Rating: ★★☆☆☆ Reviewer: Kindle Customer

"New house, new plumbing 3 years ago. After one year, the original anode rod was replaced with the product preservers rod. It lasted for one year before the water started smelling again. The plumber replaced it again, but now it is smelling again. I'm very frustrated. Not the experience I was hoping for."

"Worked great for how long it lasted, but it only lasted 2-1/2 years. Manufacturer claims life to be 5 years? I'm replacing this failed unit with another brand. Disappointed!"

Rating: ★★☆☆☆ Reviewer: Verified Purchase on April 11, 2023

"The unit looked nice, directions were clear, but mine would randomly report the electrode is shorted every 24 to 48 hours. Had to reset it multiple times. I had to return it and replace it with another brand."
