This replaces a previous Drake, because the tank cracked accidentally. Flushed flawlessly for aver 2 years. I then tried another brand that was touted to be good, but that failed miserably. Again, I'm very pleased with this Drake. Whereas the previous Drake's lid did not fit well (a mild cosmetic problem) this one does fit well. One minor problem: It took replacing the very hard rubber washers for the screws that attached the tank to the bowl with a softer rubber brand because of slow leaking that I couldn't otherwise fix. The service at Wayfair was very efficient and helpful. Toilet arrived extremely well packed. Highly recommend both the toilet and Wayfair.
