The customer service from Emily was outstanding an absolute 5+. She responded very fast and was clear in communication. I rated the product a 5 but would have put a 4.5 if I could as everything is quality about it, but it doesn't keep the beverages as cold as my Yeti did. This is a minor complaint as it still keeps it much colder/longer than a glass, but not as cold as others that could keep the ice in it all day. I ordered a total of 50 in various colors.
