leaked terribly at 2 months

Reviewed in the United States on November 7, 2023

Verified Purchase

Putting it in was easy. Worked perfectly to replace a Kohler brand kit that was only about 2 years old. And then at about 1 1/2 months, it started to drip incessantly. Leaking only worsened to the point where it ran nearly non-stop. Bought a replacement like this one, and it was a bit different and didn't fit in the shower body plumbing assembly. So, I had to buy the Kohler branded one again. So far, the Kohler is working fine..lat less than 24 hrs at least. But the lesson is to not spend $60 and get a generic part Spend all $100 and get the name brand item. This unit was horrible. AND since it lasted over 30 days, I can't return it. All I can do is just whine (there...done). Best wishes folks!
