For people saying they wasted money because it blasts water everywhere from too much pressure, let’s use our heads please and just do a quarter-turn of the ball valve on the toilets water line. Cmon people, that’s not the products fault. It’s your own incompetence.

After being so incredibly excited about the ability to save water it was the worst disappointment ever. The concept is great but the functionality doesn't workThe pressure of the water coming out of the hose is so high that the water went everywhere except where it was supposed to.I would send it back but I threw the box awayThat is $100 I will never see again.

If we didn't require this, it would be going back. Any Tom, Dick or Harry could print one off.Might be worth $29.99.

Product was easy to install and works fine. I was a bit disappointed in that it was more "light weight" and thinner material than I expected. Reason for the 1 star deduction. I expected a bit heavier product in regards to material for the price.

I got this product because I was looking for a new toilet with a built in hand sink and discovered you can't actually buy them in the US because ... because America I guess. What an absolute no brainer to wash your hands in the clean water coming in from the street, and THEN use that gray water to flush.This is not complicated to set up and it's easy to fix if you accidentally bump the lid or something and one of the pipes pops out of place. Of course I wish it weren't plastic but it does make the sink easy to move, adjust and clean. I do use a gentle foaming hand soap with this; haven't noticed any build up or other issues though it's only been a couple of months.Clever, practical, easy to install, and amazing way to reduce water waste and city sewer costs!

I have been looking at different brands for weeks and decided to go with this one because it looked less cheap. Unfortunately, I received a used unit after paying for a new item.
