MIRA Stainless Steel Insulated Travel Car Mug | Spill Proof Flip Lid | Double Wall Vacuum Insulated Coffee & Tea Mug Keeps Hot or Cold | 12 oz (350 ml) | Black

It's the only stainless steel 12 oz mug I've come across that has a proper seal on the lid. Only downsides are it's a bit tall for some coffee machines and that it ships from the US making it pretty pricey.

i'm giving this mug 5 stars, because it's perfect for what it is. However, I wish the lid was not plastic - that stuff leeches into the liquids inside. I would feel much more comfortable with a stainless steel lid, even if the feel isn't optimal (of course, rubber rim to seal is acceptable).

Good one

We have had the MIRA mugs before and love them, they keep the hot liquids hot for a long time and do not leak. Lasted us a few years now. Probably wouldn't have had to replace, but they were looking a little old with some wear and tear on the outside. The only problem is why they took so long???? We ordered Dec. 9th and never recieved them till Dec. 27th!!!! Received 3 other pkgs with that order, so I'm assuming this was all on Amazon and not the seller! Sure glad we are having our Christmas later this year

It’s an OK mug, no better than my Starbucks mug I love but they quit making. This Mira mug well I like the lid and the hole, but the lip to cover doesn’t seem to be a tight fit and I tend to hit my nose on it. Not a total deal breaker but I’m still on the hunt for a mug that stays hot, fits my kuerig and a lid that I can twist easily with carpal tunnel.
