### ⭐⭐⭐⭐⭐ Works as a replacement for the "Homelody" shower valves
*by E***B on 14 November 2024*

The person I bought my house from installed a very cheap shower kit that is sold on Amazon under the "Homelody" brand. They don't sell replacement parts, which was a problem because it leaked from day one. This cartridge fits those valves and fixed that leak.
