I bought this for my co-worker and she loves it!

Great Cup

This cup is a great conversation starter. Having red hair, and being an avid water sports gal, it was highly appropriate.

Kathleen Cochran (Palmdale, US)
Great tumbler!

I love this cup! Took it on a beach camping trip and was very pleased. The days were hot, but this cup kept my drinks cold, and my ice lasted for hours. This lid is great at not spilling, which is important. Plus, it looks great, so that's a nice bonus. I love it enough that I have now ordered a second one. I would definitely recommend it.

I love this cup and the design on it! I would buy again!

surprisingly (to me) good thermos

I bought it because it was cute. I'm thinking about another one because it is so effective at keeping cold things cold (I have ice in it the next day!) and pretty good at keeping coffee hot for several hours.

What I REALLY recommend it for is the lid's seal - I stupidly put my coffee filled thermos in a shallow cup holder one morning while running late for an appointment. Hit the first stop sign w a good hearty break and the thermos went flying. I was cussing a storm (in my best siren fashion) and grabbed the thermos expecting coffee everywhere but I had slid the little stopper closed and I mean no coffee anywhere it shouldn't be! That's when I decided I'd get another for me and probably add this item to a gift list for siren-friends.

Highly recommend.
