So far, we love these cups!  The blue color is pretty.  I like that the cups are white on the inside but blue on the outside.  These cups are well designed.  They are not very heavy but have a wide base which makes them stable.  I like the large handle as well.  Also, the 18 ounce size is great.  I wanted a little extra room in the cup and these are perfect.  I searched for the perfect cup for us and am so glad I found the Dowan brand!  As for Wayfair, the order process was straightforward and the shipping time was as stated.  I would order from Wayfair again.
