Second time I've ordered love the cups. Wife love the cups. People always think they are cool and fascinating how they work. They really do work as advertised. Even the ones we have that are six months old still work and function like brand new. Wont be my last order.

great mug keeps coffee hot for hours

I ordered two and used this summer...loved them. They kept my drinks cold on the hottest of days and I love the no spill bottom. So, l ordered three more for Christmas gifts

Two one year olds running around with a grandpa who is too busy playing with one to see the other dumping his drink!! This mug is such a spill saver! Shipping was faster than I expected...spectacular product!

Great service!
