I recently had to replace an old toilet that just wasn't performing (solid waste just wasn't making it down). I initially purchased a kohler cimarron but after reading more and more, primarily this site, I took it back (prior to installing it), bought the Toto Drake and installed it.
All I can say is, "thank you." This toliet performs. Upon the first flush, I wasn't so sure it could do the job. But during the real tests, it's doing the job and has yet to clog or fail to get solids down.
