## Customer Reviews

### ⭐⭐⭐⭐⭐ Very easy to fit
*by D***Y on 11 May 2025*

Easy to fit and adjust. From draining the tank to the first flush took about 15 minutes

### ⭐⭐⭐⭐⭐ All good
*by A***T on 21 April 2025*

The instruction sheet is tiny print, but otherwise a cheap plastic unit that fit exactly as expected.

### ⭐⭐⭐ NOT WHAT IS SEEMED
*by T***. on 13 June 2025*

Although it worked quietly and fine to begin with, it subsequently became very noisy, with jarring noises as it flushed. Despite trying to adjust it, nothing worked until I replaced it with another type, but still with an internal overflow.
