MiiR, Tumbler, Vacuum Insulated, Stainless Steel with Slide Lid, Cup Holder Compatible & BPA Free, Black, 20 Fluid Ounces

Absolute quality. Keeps your drink hot, easy to hold, fits in all cup holders.

This tumbler retains ice for at least 24 hours. I’ve learned to use ice in it sparingly because of that. It also keeps coffee hot for a long time although I haven’t tested that much since I really only use this for cold drinks. It has a nice solid feel to it and it looks great.The instructions suggest hand washing but I put it in the dishwasher (top rack) anyway and it’s been fine. I have a Yeti that’s almost identical to this (including price) so I have to compare the two. The only difference is that I like the lid on the Yeti a little better. The Miid lid is a little shallower and the opening of the mouthpiece isn’t as crisp as the Yeti. That being said, the MiiR still warrants 5 stars.

its a fine coffee mug if you dont mind coffee on your chin and lap.

I typically brew my morning coffee in a Chemex and if you've ever used one of those, you know that the coffee tastes great but keeping it hot is tricky. Not any longer! My MiiR tumbler keeps my coffee nice and hot for hours, and it fits in my car's cup holder! This is exactly the travel tumbler I've been wanting for years now. It's durable, solid without being heavy, sleek, and classy-looking.My only complaint is that the slide lid moves a little too easily. I'd love for it to hold its position (whether open or closed) more firmly, but that's a minor issue and is probably unique to my particular tumbler.

Miir coffee cup keeps your coffee hot or you ice water cold! Works as it should and has a nice finish and quality build! No leaks, easy to clean, and would make a nice gift! I would definitely recommend this cup!
