Good product. Hot a terrible stays warm for the entire night or whole a day. My only complaint is with the cover - while it works okay for the most part, it is super difficult to clean especially if you drink hot coffee from it. Also the straw that came with it is metal so it might scratch the cup on the inside if not careful.
What more could I ask for! This cup, or should I say vessel, works like a charm when I wish to carry liquids in a mobile device! I have yet to figure out how to carve a container similar to this out of rock so until then I will stick with this.
This tumbler holds up to the high end ones. It has a great seal. I've spilled it on my desk and not a drop comes out. It's well built and watertight. Keeps my ice cold all day. Sometimes I want the ice to melt quicker LOL! Highly recommend it. The reduced bottom makes it easier to fit many cup holders.
Have had it for a couple of months now and seems great. Keeps water hoter all day, the finish has held up nicely and I enjoy drinking from it. The lid seems to be nice but I tend to use it without the lid anyway. Great tumbler for the price.
