## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to install
*by V***Y on 8 June 2026*

Easy to install and well made

### ⭐⭐⭐⭐⭐ Good quality
*by R***K on 19 April 2026*

Good quality toilet flush. I've using it more than a year. Works quite nicely.

### ⭐⭐⭐⭐ European fitting.
*by A***R on 6 August 2024*

I have a standard Irish toilet and I wanted to get a push button system instead of a lever (young kids, struggling to use it). Saw this at a great price and said I'd try it. It arrived the next day (I have Prime) and I went about installing it. All was going well until I came to the coupling plate (the silver bit that connects the cistern to the toilet) because this kit does not include the plate, and the one that is used on standard Irish toilets is too small. I COULD NOT get a plate to fit over the new fitting in any local plumbing supplier (as it is a EURO size) so I had to improve and make the hole on the old one a bit bigger with the help of the hacksaw. Once I got this sorted, it was a breeze. It works really well but perhaps the button push is a tad on the hard side to push. All in all, it's good but be aware of the dreaded coupling problem.
