Corkcicle Classic Triple Insulated Coffee Mug with Lid, Matte Black, 16 oz – Stainless Steel Travel Tumbler Keeps Beverages Cold 9+hrs, Hot 3hrs – Cupholder Friendly Travel Coffee Tumbler

The drink slot is not rubberized - if it tips over while closed it leaks. Returned mine immediately.

Beautiful colour. Works exactly as promised

Me gusto mucho, amo mi vaso

Editing my review due to new developments... Below you can see my initial review (I gave it 5 stars) and I still like this cup BUT about 8-10 months later (not sure exactly when it started) the inside of the cup got covered with rust!! For a long time I though this color was coffee and tea stains until I started noticing the taste of it! So gross and disturbing!!! who knows how long I've been drinking rust... :(My previews review:I have this cup for over 4 months now, and I use it every single day, so I feel its safe to declare it is perfect! (for my needs).1. It keeps drinks HOT for hours! Never cease to surprise me. I actually need to add some cool water to my tea, otherwise I would have to wait for 2-3 hours before I can drink it! Also, keeps drinks COOL for even longer! I leave my cold coffee in the car that's parked outside in the sun and basically becomes an oven. I come back after 3 hours and the drink is exactly as I left it! Amazing!2. The lid is not spill proof because it has an opening for drinking, but it's very tightly sealed, and even when I dropped the cup a few times on my desk, spillage was minimal. I cary it from the car to the office desk so the lid is perfect for my needs. Also easy to clean, the silicon comes off and back on easily. Very smartly designed.3. The sipping opening feels nice to drink from and good size.4. The straight sides makes it easy to grip (did I mention smart design?)5. I never get any smell lingering or after taste, which I'm very sensitive to.* I don't drink any sugar or dairy so I guess if you do you might get other results with cleaning and aftertaste, but I would bet you will have no issues.

At first I really loved this cup. I still do love the inside, which keeps my ice in my water cold all night long. However, I got this 40 days ago and the bottom rubber is coming off. May be a dud but hoping the customer service for Corcksikle is good enough to send me a new one.
