Review: Excellent tumbler - stylish and functional! - I'm really happy with this Miir 16oz insulated tumbler. The design is clean and modern, and it feels very high quality. It keeps drinks hot or cold for a long time, and the press-fit lid stays secure with no leaks during normal use. The size is perfect and fits well in my car cup holder. Easy to clean and great for everyday use at work or on the go. Highly recommend!
Review: Convenient, easy to clean, spill resistant - I love this mug. It's insulated, but it's fairly thin insulation. This keeps it from being too bulky, but it still manages to keep my coffee hot enough- I don't need my coffee to be scalding hot though. It's stainless steel inside so it's easy to clean but there's a coating on the outside so it doesn't feel like drinking out of a metal mug (I don't like drinking from metal mugs). It also feels very nice in the hand and doesn't get too hot on the outside. I had a previous version of this mug that didn't have the close-able cover on the lid, and if I took it in my car when full, some coffee would splash out. The addition of the sliding cover fixes this issue, and is the main reason I replaced my old one. If you tip it over, coffee will slowly leak out but if you stand it back up quickly enough you might not have any spill out. The lid doesn't screw on so it's just a gasket/friction fit but it's quite secure. I don't think it will come off accidentally, unless you do something extremely violent like dropping on the floor. There's very few parts and pieces so it's relatively easy to clean.

### ⭐⭐⭐⭐⭐ Great buy
*by K***K on March 11, 2026*

Love this tumbler. Bought it specifically for my daily coffee. It has held up great. The temp stays as it should, it is not dishwasher safe must wash by hand but a quick rinse usually gets the job done. Durable, I've dropped it twice and only a small ding on it.
