Love the size and the flip straw. Love that I can keep the straw folded down so as not getting exposed to stuff.
I would recommend this to a friend!

Defective

I own many Stanley cups and this one although pretty is a huge disappointment. My water doesn’t stay cold at all. Ice melts within the hour. It’s brand new and now feel like it was a total waste of money.
