These cups are great and are now a favorite in the household. The construction is very sturdy. We purchased both the chocolate and black lab cups and hope to see yellow labs soon as we will purchase those as well. Now the only other thing is for the juice size!!!! I do highly recommend them for their construction and although they say dishwasher safe, they are too nice to try it -- handwashing will ensure the integrity of the cup.
So happy with the insulated tumblers! True to the advertising, they came out of the dishwasher with no fading or cracking and kept cold soda cold with no ice. I am very happy with these. :)
