Customer Review: Very cute insulated mug!! I love the color of it! Keeps my coffee nice and warm in the mornings! I like the size of it and I really like the locking mechanism on the lid to prevent spills. I’ve tested it out and no leakage at all!
Customer Review: I LOVE this cup!!! As someone who likes to just throw stuff in my bag, this cup is completely leak proof and can be upside down in my bag and not spill. I’ve used it for both hot and cold drinks, it keeps it cold or hot for at least 4 hours–I can’t attest to any longer since I usually drink it within that time frame.It’s a little on the pricey side, but the quality is totally worth it.

Customer Review: This is a flipping bottle, and it does exactly what a bottle should do. It does not leak. Not in my bag, not in my car, not when I knock it over like a clumsy raccoon. Zero spills. Zero regrets.Cold stuff stays cold. Hot stuff stays hot. I put ice water in it and hours later it was still cold enough to make me suspicious. I put coffee in it and it stayed hot long enough for me to forget about it and burn my mouth. That is on me, not the bottle.It is lightweight, easy to carry, and does not demand attention. No weird lids, no surprise drips, no emotional journey. It just quietly does its job like a responsible adult.If you are looking for a bottle that sings, tracks your hydration, or changes your life, keep scrolling. If you want a bottle that works so well you forget to think about it, this is the one.Pros:Does not leak, everKeeps drinks cold and hot like it promisedLight and easy to carryCons:None, unless you expect a bottle to do your taxesBottom line: Wanting more from this would be selfish. It is a bottle. It bottles perfectly. Five stars.
