Firstly, these cups are amazing quality. They're actually bigger than I expected them to be, and the designs I ordered, Black Leopard To-Go & Purple Gradient To-Go, are really cute. They work like a charm as well, it kept the iced coffee I had cold all day - I got the coffee at 9am and still had ice in the cup by 4pm! The only negative opinions I have is that I ordered two at the same time, but never got the second one until I sent an email asking where that second one was (which was a three month gap). I got it quickly enough once they realized the error, but it didn't come with a cover. That ended up being okay, as the second one was a gift that was just going to be used as an iced coffee insulator, but I am a bit confused as to why a cover wasn't sent with a cup. All in all, it is a great product and I would suggest getting one.
