    I was looking forward to getting this mug for the locking mechanism. That feature works great, however, the body of the mug has a huge design flaw.

    As you can see, the outside of the mug is tapered, but the inside is not. As a result, there is less insulation (vacuum) between the outer and inner skins toward the top of the mug. All the heat gets lost to the environment around the neck.

    You can test this for yourself. Pour hot water in the mug and close it. Wait about a minute and touch the body toward the bottom and compare that to the temperature around the neck. You'll feel the temperature differential.

    This heat loss causes the hot liquid inside to cool down very quickly. Piping hot coffee becomes warm just after an hour.

    I ordered this mug on the Contigo website, and was anxiously awaiting its arrival! To my dismay, the shipping department failed to put my suite number on the shipping label, and the item was returned to the warehouse. As soon as I found out, I called customer service. The gentleman I spoke to was extremely helpful, and boxed up the items himself and shipped them to me.

    The mug is fantastic! It keeps my drinks hot for a great amount of time. The locking mechanism is a great feature, and its definitely leak proof. It has a very sleek look and feels good in the hand. I also like the fact that the mug does not get hot when it is carrying a hot beverage.

    I looked for leak proof travel mugs for so many years because I took public transportation to work and would have to put my mugs in a knapsack or bookbag and they always leaked! I had given up until a year ago when I recieved this mug as a gift! I was amazed at how hot it kept my beverage and how it NEVER spilled! I've dropped it several times with no damage! I just love it!

    I've been using the Contigo travel mugs for at least 5 years now and there's nothing on the market that compares to it. I have just started using the Aria 20 oz. mug within the last year or so. I like it better than the West Loop because it has a smaller lid (in diameter) and is easier for me to grip to open and close. I would love to see more colors. My first Aria was a black one and now I see there's only 1 color option (I also have that one). Would particularly like to see it in the deep red color or the latte color. I use one for just water and my 2nd one for coffee. I love this travel mug, can't live without it! Thanks.

    I apologize for carelessly leaving you on the train and then thinking that I could replace you with the flashy colored West Loop. Yes, you have an amazing locking lid and stay piping hot HOURS longer than West Loop but would it kill you to spice it up every now and again with some amazing color options? I'm glad you're still around for me(to purchase). I will not stray again (especially if you consdier offering up some more color options). I love you Aria!!!

    By PlainMe

    I love this coffee mug/container. If there is any complaint, it is that it keeps my drink too hot, for too long. But, that what it is designed for. I don't drink my coffee until it cools down. Still, not a complaint -- only an observation.

    The lid is leak-proof and the locking feature is incredible. The rubber bottom keeps it from slipping around, just like it was designed to do.

    I don't have anything to add. Great, great, product!

    By Stan The Man

    I love the new bottom!!! The new grip bottom doesn't slide around in my bag or anywhere else I put it. It stays where I put it and that's what I like. Please don't change it... I love the locking mechanism and the smaller top. Could you please add the dark bronze color and the clear bronze button? I would like to buy another one if that were possible.

    By Chuck

    I love the new locking top which I thought would make it great for a bag BUT, the new rubber bottom makes it really difficult to slip in or out of the bag because it grabs on to everything. I'm going back to the Westloop; not as spill-proof but at least I can get it in and out of my bag easily.
