ArticFox 30 oz Stainless Steel Double Wall Vacuum Insulated Tumbler for Sweat-Free Use - Upgraded BPA Free Slide Close Splash Proof Lid For the Perfect Travel Mug.

Awesome product, keeps my coffee and tea warm for hours. The only thing I could say might need a little improvement is the leaking. When closed, it does INITIALLY leak a few drops, however this is not enough to lose respect in my opinion as 30oz could make a lot more of a mess.Fits perfect in my cars cupholder, I have not noticed any rings, and when I have hot coffee inside the cup you wouldn't know from the outside. Great quality and finish, really happy I bought this product and will be buying more.

It works as advertised but within first two hours of use it created a hairline fracture through lidI did not drop it and it is still useable just seems like a strange malfunction.Overall though it keeps ice, ice cold overnight and that is all I needed it to doWould still recommend

Okay, so I was a bit skeptical about this tumbler and its ability to keep drinks cold, but after one use I'm certainly impressed. Got this on Thursday and took it to work on Friday. Around 10am I made iced tea. At 5pm there was still a fair amount of ice left in the cup even after the liquid was gone - I'm sold! Tumbler looks good and has a nice weight to it.

I received my new tumbler in a very timely manner, before the allotted time, which was very impressive! I've use it a few times now and it does exactly what you said it would do! For the price it's the perfect tumbler and it serves all my drinking needs!!Thank you Articfox,L.E. Hawkins

It does everything you say it will do. It is a very easy cup to clean and dry at the end of the day. Ready to go the next morning.

Great cup. I put ice water in this cup and 12 hours later there was still ice! So much cheaper than other name brand cups and a great price

I read reviews on these types of mugs about their effectiveness on hot and cold drinks, but I wanted to prove it to myself. I put in ice water in the afternoon and set in a room temperature environment. Still ice water the next day. While at work I put in hot tea and it was still piping hot more than 3 hours later.I am definitely pleased.

wife loves it. happy wife, happy life.
