MiiRCamp Cup, 12oz - Double Wall Vacuum Insulated, Stainless Steel with Splash-Proof Slide Lid

I spend a lot of time being outdoors and being cold and wet, and a hot drink is often the morale boost of the day. I've tried lots of insuated mugs with various success, but this one is by far the best I've used.To look at, it's just a normal stainless steel mug, but the insulation is phenomenally effective. On a very cold day you can fill this with hot tea and it stays hot. The only slight downside is the insulation is so good that you won't be able to warm your hands as you drink it. It's quite incredible how well it works.Build quality is excellent, and there are no plastic parts to break (other than the lid). It's easy to clean with no nooks and crannies for debris to get into. it's an expensive mug, but it's the last one you'll need to buy. Excellent item.

It does keep warm for 5-6 hours and has a sleek and nice design. This is my 3rd MiiR mug after gifting them.

A cup so nice I bought it twice…one for me and one for my boyfriend.

Keeps my morning beverage hot for at least an hour, drinkable for 3.

I bought a new Keurig, the one that reads the code from the top of the capsule and brews the coffee according to a custom recipe for that coffee, and connects to Alexa, etc. But the spout to base distance was reduced, the steel cup we used to use wouldn't fit anymore.This cup fits perfectly, and is well made. It holds all of the coffee that the keurig will produce, and is exactly what I wanted.It is easy to pour coffee out of this cup into another cup. It looks good and seems well made.

Despite this getting great reviews & being sturdy, it had some big cons & so no one in our household liked it. I’ll donate it as we used it several times. The squared-off handle is not comfortable to hold, it’s heavy, and if you want to warm up your liquid later, you can’t put it in the microwave. So for those reasons, I went with a different mug which was made of double-walled acrylic and I’m very happy with that.
