    I have purchased and liked numerous Contigo products. However, the Aria is not one of them. Even the (2) replacement lids Contigo graciously supplied me leaked. I cannot determine if it is a bad design or poor quality !

    I have the first Aria that has gray trim. I have used it daily for almost a year. In fact, I don't drink out of anything else. I love the fact that I can gage my daily intake of water. Besides keeping beverages ice cold or hot I love the autoseal and that I can lock it while traveling.
    By having the rubber gripper on the bottom I know it won't travel during natural vibration of the airplane or car. Please go back to this original lid production as I buy these as gifts for family and friends.

    Really liked this mug when it was new, but after only a few months, it started leaking from the bottom of the cap, leaking from the mouth/liquid hole that you drink from, and it started leaking BIG time (like explode all over you and your clothes kind of leak) just recently. I have always been pretty particular about cleaning and taking care of it; I have brushes that I thoroughly clean the lid with. I even let the lid soak in water after every use... To no avail, it won't stop leaking. Thought it would be great for hot liquids (coffee, tea), to keep them warm. Oh well.

    I don't understand it, I have used Contigo mugs before and I love the leak-proof design. This particular model leaks both from the seal and from the vent - quite a bit actually. I wrap the mug in a paper towel and it is half soaked by the time I am finished.

    I love Contigo and their products, but this mug in particular seems to have a flawed design. I knocked it off a desk once and when it hit the floor a HUGE dent was in it. I have other stainless steal contigo mugs that I've dropped that didn't end up with a massive dent in the side. I recommend trying the West loop, that thing has stood up to all sorts of drops on asphalt, tile, etc. The finish on that chips off though.

    Great for car and very easy to handle-keeps coffee warm for along time!

    By asdfghjkl

    I have really liked this mug, but never realized just how great it actually is. I made some tea about an hour ago and put it in my mug. I just got out of the shower and went to drink and it is still just as hot as it was when I poured it. Incredible!

    By Michele

    I thought I was gonna hate this mug when I got it for Christmas but now it's the only one I want to use! I waste much less coffee because it simply doesn't get cold! I don't understand how it works but it does. I'm on this site to purchase a few more...thanks mom!

    By Swamper

    Awesome mug, but I have been having issues with the seals on the past few mugs I got, and have been getting coffee all over me. May have been a bunch of bad seals. Love the mug been buying them from the beginning.

    I recently knocked my Aria Stainless Travel mug full of hot tea off a shelf. It landed lid down on my brand new MacBook Air.... not a drop spilled out. I give the product 9 stars even though the rating only goes to 5.

    And it kept my beverage hot well into the evening.


    By Erik

    Great mug, truly keeps the beverages cold forever. However; I put this in my cupholder on my mower which it fit perfect but all the vibration had it rubbing up and down on the holder (hour time) and all the paint ( I got the blue one) that was within the cupholder chipped off. This was my first time using it, so it kind of stinks it already looks 5 years old, but it still keeps it cool at least.

    By Paz

    What a find! Awesome. I have used mine everyday since it arrived. I carry earl grey tea, and there is no spillage, it keeps warm, just a little small however I notice there is a larger flask for sale and I wouldn't mind that also. Simply the Best travel mug/flask around.

    5 stars for the first couple years that I owned it. I even bought another for my husband. It was leakproof and I loved how it locked! But after about a year and a half to two years it has started leaking out the bottom of the cap. My guess is that when I put hot coffee in it, it starts to pressurize because of the steam and something happens to the seal. I can no long throw it in my bag on the way out the door because by the time I get to work the bottom of my bag is soaked with coffee. Sometimes I forget it leaks and it's quite unfortunate. Maybe it's time for a new one, but I will probably look into other products. I need something with a longer life span that's reliable. It was great while it lasted.

    Love contigo. Mugs are awesome with amazing heat retention. However, I'm not in love with the top on this model. It feels flimsier than others I own, particularly the button.
