We've had the elongated, comfort-height Cimarron for about a year now and are very happy with it. It was very easy to install. I especially like the bracket on the bottom of the tank - no bolt holes in the bottom of the tank to worry about.
The flush is great - have not had to plunge a single time. It re-fills quickly and quietly. It's true that the bowl wash is not as good as some others, but it really isn't that bad. A quick brush every once in a while sure beats having to plunge! And our local HD carries the replacement flapper in case that ever needs replacing. I would recommend this toilet and will probably be installing another one when we get to the next bathroom.
