The seat bottom has only 2 rubber supports (my old one had 4) which will decrease its overall lifespan and comfort. The hinge is slightly taller than the seat itself which makes it sit at ever-so-slight an angle. Could be fixed with an extra rubber/plastic washer (I repurposed my old ones and that did the trick.) Overall, not a great product, but the best value (some others online go for 3x 4x the price!)
