Best travel mug I ever bought!
599264
Keeps coffee hot for hours and cold things cold for hours.  Well built. Absolutely no spills.  Have bought 2 more for us and 1 as a gift!  Note: the plastic one by Contigo is no spill, but doesn't keep things hot/cold for more than about 45 minutes.

My coffee is still hot after lunch! Worth the cleaning efforts you have to go through. Best travel mug I have ever owned, and believe me I have tried MANY.

Holy CRAP!!!!! This travel mug is AMAZING! hot coffee will stay hot for quite a long time and has stayed warm for up to 6 hours at least. great mug! the anti spill function has saved my butt more times than I can count and is truly and honestly ANTI-SPILL. I can fill this mug up and turn it upside down and nothing comes out. its fantastic!

5 Stars.  I've had mine, in midnight blue, for about 3 years now.  Best travel mug I have ever owned.  And I've had at least a dozen of them.  It is incredible how long hot coffeee stays hot in this thing!  If I fill the mug at 6:30 am, it is still drinkably warm/hot 5+ hours later.  Yes the paint chips off the outside.  But that's because it works so well, you use it every single day!  Next one I buy will be Cranberry.  Yes, they're that good!  I found out about it because Popular Mechanics rated it the best travel mug they tested out of 3 top level mugs.

This is by far THE best travel mug ever created. It definitely keeps my beverage HOT for 4+ hours, warm for almost 7, and a beverage cold for 8-10 hours. Stainless steel insures that there are no harmful plastics and chemicals released into your beverage, the top is 100% tight & leak-proof but at the same time has a push-release for easy access instead of having to screw it on/off.

This is easily the best travel mug I've had. I can pour coffee before I leave for work and it's still warm at the end of the day. The lid is very easy to wash and you can ensure that you're getting all the crevices. I prefer this over the snapseal mug because you can't clean the lid for that mug easily. This mug also has a sleek appearance and grip right in the middle. I liked it so much I bought as gifts for three others!

I didn't get this from Amazon, but I'm here for a second one! I love this mug. It is my favorite travel mug by far.

I've had it for about 6 months now and have had zero problems. It doesnt leak, no peeling paint, no mold (all issues noted by other reviewers) and it keeps drinks hot all day without transferring the heat to your hand.

The lid is top rack dishwasher safe. The mug is hand wash (however i sometimes put it in the dishwasher...)

I absolutely love this mug.  I bought it several years ago and it still keeps my drink hot pretty much all day (it is hot for about 5 hours and then still pretty warm after 8 hours).  I have recommended it to several friends who have purchased it and love it too.  It never leaks and is easy to clean.  I don't think I will ever buy any other travel mug.

Best travel mug I've ever used.  I seriously can not even believe how well this works.  I wanted to put this insulated cup to the test , so I did my own little experiment.  I filled my cup up with ice cubes and water and then put the lid on it, and then just set it on the counter in the kitchen.  The house is not air conditioned, and it was an 80* day.  I set my cup out at 2:00pm.  I went back and checked on it at about 4:15pm and then I forgot about it and didn't go back to check it again till 10:00pm, and it still had solid whole ice cubes!  I couldn't believe it lol.  I left it out for the rest of the night then and when I went back to it late the next morning, the ice was melted, but the water was still ice cold.  And it really is sweat proof because the outside of the cup stayed dry the whole time, and like I said it was an 80*+ day.

Perfect travel mug!  I can't believe how long your drink stay hot.  Even with the top open for a couple hours, my drink was still hot.  I would highly recommend this product.  Although, if you get the "skinny" version, know that it will wobble in a standard car coffee holder.  That is seriously the ONLY thing that needs improvement.

I love this travel mug. Hot beverages stay hot & the snapseal keeps it from leaking so I can throw it in my purse or bag without any leaking.  I love it!

i have about a dozen coffee travel mugs, but THIS ONE is THE BEST!
it's holds 20 oz, and works well for both HOT & COLD drinks - i've tried
both hot & cold stuff and it DOES WORK!  it seals b/w sips, so you won't
have to worry about {oops!} spills!

nice slim design fits in the cup holders, too.

I honestly cannot imagine using any other travel mug ever again!

Pros:
- sleek design, fits well in hand
- tight seal / locking mechanism prevents spills  (i've have dropped this all over the place and actually challenged friends to try and shake some coffee out when it is locked, can't do it!)
- built in flow control (there is an insert that makes for easy sipping and prevents a too much from coming out)
- keeps things HOT.  Like I make my coffee at 6am and depending how many times I open it, it can stay very warm until 4-5pm.

Cons:
- You could actually burn yourself HOURS after putting hot liquid in.  I tend to put in my coffee with two ice cubes so it is the perfect hotness when I'm ready to drink it.

Best travel mug out there!  Love that the lid can be taken off, opened up, and thrown in the dishwasher.  So easy to clean and it keeps coffee hot for hours!

Absolutely the best travel mug - EVER!  Keeps hot beverages warm at least 12 hours or longer.  Unbelievable product.  Note - disassemble the lid periodically to sanitize (dishwasher safe).

Needed a travel coffee mug, read a few reviews and figured this one would work. This mug is awesome!! No spills, no leaks, easy to clean and it keeps my coffee hot! I drink my coffee slow and it's usually cold about 1/2 way through my cup because I drink it so slow... Well I've been working on the same cup for over two hours and my coffee is still hot!!! Super happy with this purchase :)
