On the whole, this fixture fits what I was looking for in a one-piece toilet,  a low water closet with a streamline-looking base.  However, the back half of the base has the usual convoluted shape of most toilets, which is not evident from the angle at which the provided photograph was taken.  Thus the 4-stars.  It may be that overall base sleekness is difficult to avoid at this price for functional or installation purposes.  It's operation so far is top notch.  It uses minimal water but flushes effectively, and it's small size makes it ideal for a small bathroom.  The inner mechanism of one of the two such toilets I ordered was damaged, but my installer was able to substitute a compatible mechanism from a local big box store.
