### ⭐⭐⭐⭐⭐ Better than expected - a TRUE water saver
*by K***C on 18 April 2026*

After just a few days use, i am compelled to write a review on this product. 1. It is well made and look and feels high quality 2. The detented adjustments allow a wide array fitment, and the detent positions hold very well 3. The flapper is adjustable for the length of time the flapper stays open.. which is nice 4. Easy installation... almost too easy Now... the primary reason for my review is the following 5. The longest "flap open" setting of 10, leaves about 3 nches of water in the bowl, which made me concerned.. as this was the longest the flap could stay up ( 10 was Max) BUT 6. I watched the actual bowl flush and it was a complete, full length flush.. 7. I confirmed this by leaving the tank cover off for three days, and the tank would have about 3 inches of water BUT still allowed a complete flush This is a real water saver, as the flapper it replaced would drain down to about an inch.. I was concerned that the flapper was closing too quickly to allow a full flush BUT it does allow a full flush Great product
