It works! Don't forget that you most likely need to cut the tube shorter so make sure you have something to do that with.

Terrible! Don’t waste your time with this product. They ask you to provide a size which I did and they just send multiple sizes that I don’t need. I have four toilets that all needed the same size and I get six of different sizes. Plus it took two weeks to get them delivered and they don’t let you return.

This is a great product that worked out fantastic with the increase in water that really saves in the long run. I wanted to say that the company behind the product helped me every step of the way and made sure I had the exact size I needed and you can call them at anytime for their technical support and they are there for you. It doesn't get any better than that. Thank you so much .
