CorkcicleClassic Triple Insulated Coffee Mug with Lid, Matte Black, 24 oz – Stainless Steel Travel Tumbler Keeps Beverages Cold 9+hrs, Hot 3hrs – Cupholder Friendly Travel Coffee Tumbler

Big fan of this brand. Iv been using a different cup for a few years and was so excited when I saw this as an option while looking for a new travel coffee cup. One possible downside is that it says that it's dishwasher safe. However, the sticker label literally says not dishwasher safe and hand wash only. But, I have only handwashed my other stemless travel wine cup and have not had any issue with the coating peeling. It is drip/spill proof as long as u don't hold it upside down or lay it on its side with liquid in it. I definitely agree that it stays cold for long periods and hot long enough to get through my drink without needing to reheat the contents. I personally think it is a good value for the money because its cute and functional with the flat sides for grip.

Excellent

Great mug that keeps my large coffee hot until I am finished drinking it. Cleans in the dishwasher. Fantastic.The slider closure doesn't really seal. Perhaps it helps ever so slightly with temperature control. The mug this replaces merely had a hole with no closure so I am not missing anything. Not really a travel mug though. More often than not I don't even use the lid. I just want the insulated sides to keep coffee warm until I am finished. It has a non-slip rubber bottom that makes me nervous - a bump on the mug could lead to a tip over instead of a slide.

Wife loved it! Now she can have her large coffee latte and it will be warm a long time. She uses it every day.

Best cup I’ve ever bought! The quality was obvious the minute I opened the box.

No handles to get in the way of sitting in a holder

Amazon warned on the listing that this blue mug was frequently returned. I bought it anyway and it's been perfect. I already had this Corkcicle mug in stainless and the dark blue one is just the same.This mug has a triple wall which makes a big difference in how long ice stays solid in liquid. A double wall container is not nearly as good. Corkcicle mugs are triple walled and that makes it worth their somewhat higher price.

Keeps cold stuff cold and hot stuff hot for a long time. Easy clean up. Outside and inside still looks brand new even after almost 6 months of daily use. Top fits well and is strong....but it's not leak-proof. My only complaint about this product is the slider on the lid. It has a nice shape to allow for open and close, but it offers no sealing, a small vent, and tabs that I am certain with wear and break in the future. I use this mug everyday. Coffee at work, and a cool sip on the weekends. I can't believe they got 99% of this product right and missed that one minor detail. Hot coffee across your bare lip in the morning is definitely a wake up call. Having said that, after purchasing this i am now the owner of 3 more of their products. They all have the same great qualities and features
