The 4 star rating is relative to the price paid.  This was very inexpensive for a king size.  The print is pretty.  The dark blue is really dark (almost black).  It is very thin so I pare it with a light weight blanket for summer sleep.  Not nearly heavy enough for winter.  If I had paid more, I would not have been happy with how thin it is.
I did wash it and still found it acceptable size to cover our mattresses.  But we don’t have those massive 20” mattresses - so if you do have a very large mattress, this likely wouldn’t be large enough for you.
