It's the most beautiful tumbler I have ever owned. I feel special using it at social events. It makes me look important. You even put my name on it which totally personalized it to me specifically. Thankyou Matthew Curtis for the beautiful tumbler. Keep up the great work and long exhausting hours!! I give a full 5 stars! (Only one improvement would be a better sealed non leaking lid like the yeti lids for if tumbler gets knocked over. I did that replacement at extra cost to me.)
