MiiR, Tumbler, Vacuum Insulated, Stainless Steel with Slide Lid, Cup Holder Compatible & BPA Free, Black, 12 Fluid Ounces

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.

I purchased this size after I received a free mini one. The one I had was so small, so I purchased this one. It may not be the most popular tumbler on the market, but my main reason for purchasing was the quality. The seal on the lid is great and doesn’t mess up after going through the dishwasher cycle. The tumbler itself is also wide enough to hand wash with a sponge.

Keeps your coffee hot! I like the size and shape of the cup. It’s comfortable.

Best money spent on a coffee cup. Keeps coffee hot for hours, which is great for me because I can’t stand drinking coffee even at room temperature. Loved it so much I now have 5 cups.

Top leaks a bit but it’s a decent little cup.

This is a great mug. Keeps things hot for hours. My dad borrowed mine once and I missed it so much, my other travel mugs just don’t compare. Finally got it back and he liked mine so much he got two for himself (this size and the 12oz). One of his is blue (mine’s black) and I really like that color. May have to get another.

This is my first MiiR purchase. Love it!!! Perfect size and keeps coffee hot for hour++. Love the splash guard on lid and the cup just looks good!! Plan to purchase another soon. I have some larger Yeti tumblers but this 12oz size is just perfect! Highly recommend.

The lid was not a good fit for the cup and constantly leaks. It doesn't fit flush and should prevent a drink from spilling out, very poor quality item.
