Contigo - 16-Oz. AUTOSEAL West Loop Stainless Travel Mug with Open-Access Lid - Midnight Blue

I used to travel for work. These mugs can, if locked, be thrown into a bag with papers or laptops. I have NEVER had a problem with the auto-seal lids leaking, even in planes, where the pressure changes. The lids on the inside are mechanically designed for easy cleaning. But, I recommend rinsing them as soon as possible after consuming and beverages with milk or milk alternatives. The reason that I threw away other travel mugs, is that the drinking hole gets gross; that is not a problem with this mug. Cleaning is easy. I unlatch the lid and place the lid and tumbler in the dishwasher. (See picture of the auto-seal lid below that I have owned for years. Notice the daylight coming through the drinking hole. EASY CLEANING! ) The auto-seal lids also have the same diameter, whether you are using the 10, 12, 16 or 20 oz sizes. It's easy for storing in your home, if you have more than one. It does keep the hot drinks hot and the cold drinks cold. Welcome to the wonderful world of Contigo Auto-seal Tumblers.

Is an nice cup easy to use work exelent for coffee or tea

This product is convenient and practical. Love the size and shape. Easy to hold and won't spill at all. I can drop it in my purse or diaper bag with no danger of a spill. My sister drops one in her briefcase and says it's still nice and hot when she sits at her desk.

We really like the West Loop Contigo Travel Mug. There are lots of varieties out now and the design changed slightly over the years. We love ours so much so, that we've bought a few as gifts. My only complaint is the sip hole was made smaller on my newer model. Wish they wouldn't have done that, but still a good spill proof travel mug that keeps liquids hot/cold for hours!! You won't believe how long! Also, my husband's lid started to leak after several years of use, and the company mailed him a new one!! Can't beat Lifetime Warranty!!!

I truly love this cup. It keeps my tea hot for hours. It's easy to clean and I love the color. It fits perfectly under my Keurig and just all around a very good and durable cup. I would definitely recommend this cup for someone who makes hot drinks, but doesn't always get to drink it all in one setting. It will keep it hot for up to 3 hours based on my knowledge and trials. I love the safety lock feature. A great thing to have when you have curious kids who like to pick up your cup and drink without asking (lol)!

I had a coupon for $5 which made this cup cost $5 for me out of pocket. It’s a great non-spill cu that is worth the $10 price. I think this would not be a good cup for an older person because it takes a bit of strength to push the button to open the hole to drink from. Great for shaking up liquids if you need to do that. Keeps my coffee hot for a longer period of time.

Coffee stays hot for hours. Does not leak. Cleans up easily.

This travel mug was a great buy for me. No leaks since I purchased it and it keeps things cold as advertised. I filled it early in the morning of a very hot and humid day with ice and water. I drank all of the water and left the mug in the car all day and there was still ice in it when I got home that evening. Highly recommended!
