So dissatisfied!  The seat is not flush with the bottom, I called they sent instructions to correct (she mentioned it was an ongoing problem) the fix works for a day or two and the seat goes back!  This is the least of it!   The worst of it is that the toilet doesn't flush well and very often clogs, even worse......when you flush it spits water out at your legs!  My sincere advice....DON'T BUY THIS PRODUCT!!!!!!!
