Arctic Lava 10 OZ / 320 ML Double Wall Vacuum Insulated 18/8 Stainless Steel Travel Tumbler Coffee/Tea Mug with Leak Proof Locking Lid (10 oz / 320 ml, Black)

Arctic lava is a great name. It keeps things HOT. Better than any mug I've used. But the lid seal isn't great so it will leak liquid if you don't screw it on just right. And the rubber stopper that plugs the mouth piece when closed has started to smell moldy in just a few months. They also need the redesign the mouth piece completely so people with normal size noses don't get them smooshed when sipping.

Arctic Lava 320 ml/10 oz Double Wall Vacuum Insulated 18/8 Stainless Steel Travel Tumbler Coffee/Tea Mug with Leak Proof Locking Lid Seals in Freshness and Maintains Temperature does not correspond to seller description:1. It does leak when you put mug on the side2. it does not keep temperature of your coffee/tea3. it is warm to touch even though it says double wall insulated. It is light mug compare to different brand I have which also stated double wall and it is cool to touch when you fill hot water/tea/coffee.

A good little cup. Probably would do even better for coffee or hot chocolate, where someone would be taking smaller sips. I don't drink coffee so soda is what I put in it.. Seems well insulated though to keep soda or water, or tea cold, if a cold drink is what you choose to put in it. Having good insulation , it should also keep coffee or hot chocolate nice and warm as well. The size is very convenient as well....not bundlesome.Well, three years later and I still have this insulated tumbler. I'm updating my review. Why I didn't give it more stars to start with is a mystery. I've used this little tumbler more this Summer than ever. I like it a bunch!! I'm telling ya, this thing keeps things cold! Even after setting in the car in the heat for an hour or so the drink is still comfortably cool. Definitely 5 stars.

Take some money out of your wallet... then throw it in the trash... I just chucked mine because it began leaking after minimal use... my money would have been better spent on a different product. It does insulate well though but thats it!

I bought this to replace my Contigo travel mug, and I can't even begin to express how disappointed I've been. Firstly, there is a "sippy cup" style mouth piece that pushes against your nose anytime you take a sip. Secondly, there's an odd "nub" that is supposed to seal the drink when you close it. However every time you open the mug, it flings coffee at you. I ruined one of my work shirts strictly by attempting to take a sip of coffee. To use the cup, you have to hold your finger above the lid while it opens to prevent it from opening to quickly, or you get the coffee shower. Extremely disappointing. Will be requesting a return, as this was a wasted purchase.

This was a great solution to my annoyed feeling went filling up my larger travel mugs with the 10 oz of coffee that my k-cup provides me. I felt weird only filling up my cup half way even though I didnt want to drink more coffee. This 10oz mug is perfect. Its very cute and compact. I throw it in my purse without worrying about it leaking and it stays warm all day.

I have to give this only one star because it leaks when laying on its side. The ad says that you can seal it and throw it in your bag "without worry" but, in my case, that would lead to a big mess.I only see one other complaint of this in the reviews so I'm going to return this one and order another to see if I get a better result. If the new one is leak proof I will update this review to 5 stars.

This keeps coffee hot pretty well but it leaks around the lid seal. Removed the seal to clean and inspect it and found nothing visually wrong. Also tried lubing it with vegetable oil thinking maybe it was kinking as the lid was screwed on but it still leaks. My gym bag and clothes smell like coffee (not a bad thing necessarily but annoying).
