    This keeps my coffee so hot for hours! I leave my house at 7 in the morning and it is still, almost uncomfortably, hot at 10:00. I would recommend this product to anyone!


    First tried the contigo mug ( 16 oz.) that my daughters bought for their father. I confiscated it for myself ( he wasn't using it :) Well, I had wanted "MY OWN MUG." So for MOTHER'S DAY , my gift to MYSELF was a purple 20 oz. Contigo autoseal West Loop . I keep it @ my bedside for nice COLD water during the night ( the ice is still in it in the morning ) & when I do drink hot beverages it keeps them HOT for hours.
    I just recommended it to a couple of my coworkers this morning.... twice this week, one of them has wasted coffee on herself on the way to work. My statement was
    " YOU NEED A CONTIGO ".... : ) :) :)
    I carry it to work with me & when I go out I have it in the car... Never leaks...
    Also bought my grand-children the autoseal Kids Trekker Water bottles. Hope to buy more when they are on sale :)

    The open-access lid is great! It makes it much easier to clean than before. I use my mug with "Bulletproof Coffee" (Kerrygold butter and MCT oil) and with the old lid sometimes the oil would get stuck in the lid.

    I love the larger capacity but not the larger diameter. The original 16 oz size fit inside my Honda Fit's cup holders - this one doesn't. I was under the impression only the height had changed.

    I bought Contigo again because it was the best travel bug I've found yet, but like others have said, the lids begin to leak after a while. The Auto-seal is near perfect in the beginning but the integrity of the seal breaks down over time. I'm hoping this redesigned lid will prove more durable.

    By Gordon

    It was already pointed out by another reviewer. The bottle itself would have gotten 4 stars if not for the lid. I expect it to last longer. When going through the replacement lid, It really makes me wonder why are there so many different lid for so many bottles rather than making universal lid that fits different bottle. For example the Byron being able to fit with a Easy Clean lid to really cut down on waste.

    By CARY

    These stainless mugs with the auto seal cap are the best around. The auto seal top works great, easy to use with one hand, seals perfectly with no leaks and easy to clean. The bottle is just the right shape, weight easy to handle, fits in cup holder in car and won't leak in a backpack. Fantastick product

    By Disappointed

    Bottle is well designed but the lid is totally disappointing. Hard to clean and no lid locking for keeping the bottle in the bag. Understand that there's a new easy clean lid but it only comes with the 16 oz bottle and you need to get it separately for the 20 oz. Reusable bottle but not going green on the PLASTIC LID which only has a short lifespan of 1 to 2 months pretty much defeat the purpose and high upkeep of the lid that cost so much more than the bottles after 2 lid replacement.

    By Bark

    Keeps beverages hot forever, never spills coffee on you. The lids are hard to clean, especially if you don't clean them right away and the lids self destruct if you drop the mug. The mug is indestructible but the lids break. They are cheap to replace, buy extras.

    Dear West Loop,
    I'm sorry but you are moving into limited rotation. I admit I was mesmerized by your beautiful Lilac & Latte colors. And if I had not already experienced the hotness of Aria, I probably would have stood by you forever and rated you a solid 5! But I did. I did experience Aria. Aria stays hotter than you, longer than you. And Aria's cap locks... HER CAP LOCKS!! How can I possibly resist going back to Aria. As you are still so lovely, you don't normally leak, and you still stay hotter longer than most mugs, I will keep you... in limited rotation. Love, Me.

    I had countless other brand's travel mugs, each with hot guarantees from 2 hours to 12 hours. I can tell you, none of them kept my beverage hot for even two hours.

    Finally I took a chance on the Contigo brand travel mug, a brand I had never heard of. BEST coffee-related decision of my life. While they are rated for 6 hours, I have left a full mug of coffee on the kitchen counter before school, come back 8 hours later, and it has still been warm! I was so excited about this mug when I first got it I often showed it off to my friends, doing things like flipping it completely over and shaking it, or showing them that my drink is indeed still hot after 6 hours of school. It is also a very solid build, after over a year I've only had a little of the finish scrap off with no dents or cracks.

    Overall the best travel mug I have ever owned by a mile.

    By zoma

    LOVE this mug! I have only used this for cold drinks and ice stays for 24 hours! Never leaks, even if upside down for hours. Highly recommended.

    By Meg

    I've had two of these mugs for less than a year and have encountered many problems. Customer service is quick to respond but less than helpful unless you speak harshly to them.

    A few months after purchasing, the lids began to leak constantly. The mugs and lids were hand-washed and never dropped or beaten up in any way. Then the bottom of the mugs came loose and fell off. The lids have been replaced and I'm waiting for replacement mugs. It seems these items are not nearly as well-made as the company says.

    By Kathie

    I bought this model for my sister after she had her baby. New moms don't have enough hands and frequently miss out on hot coffee. Now she can throw her mug in the diaper bag or her purse And gets hot coffee. She loves it!

    By Diane

    This is the best mug ever. I have spent hundreds of dollars over the years looking for the perfect mug. This is it. Fabulous on the beach keeps drinks fold for hours.
    I recommend the stainless sterling color, the others chip over time. I have a bunch and use them for guests all the time on my boat. No worries of spills.

    By Tucknroll

    My wife and I have used Contigo mugs for several years. The older style was very difficult to keep the inside of the lid clean and used to get some pretty nasty stuff out of there while probing with different instruments to get into all of the nooks and crannies. These new lids are much easier to clean and the 20oz size is perfect.

    By dpeterson97526

    Bought two of these after having taken home a Roadster that had been sitting in our lost and found at work for months. The Autoseal technology is awesome. You never have to worry about spilling or leakage. Just keep in mind that if it goes in too hot to drink, it will be too hot to drink still an hour later. As I french press my coffee I usually wait a couple minutes before pouring. My wife loves hers because when left for several hours inside our black car during the summer, the drink is still cold. These are well worth the price.
