The sleek, brushed-finish, stainless-steel body of the mug fits any standard car cup holder. OXO’s signature soft, non-slip material rings the mug neck, allowing for a secure grip when drinking or unscrewing the contoured lid. The mug holds 14 ounces--room for a double-tall latte with extra foam. A marked ‘max’ line inside prevents over-filling. Preheating or pre-chilling the mug is recommended for increased insulation value. For best results, wash the mug by hand after each use. OXO backs all its products with a satisfaction warranty, and will replace or refund any returned item. --Ann Bieri

Content: I received this recently at one of our 'secret Santa' Christmas get-togethers. Up until then, I've been using the Thermos Nissan 18-Ounce Stainless-Steel Insulated Travel Tumbler almost exclusively for the past several months. I am pleased with the Thermos but I welcomed having two good-quality coffee mugs so I didn't have to wash the mug every morning before filling it up - with 2 I would do it every other morning, I thought. I will not do a comparison between the two, I only wanted to note that we do have choices when it comes to quality travel mugs these days and some are better than others.

I will enumerate some of the OXO features and my verdict will follow:

+ 14 oz. mug with a grooved plastic lid that closes tight
+ the body is double-walled steel with vacuum so it keeps a beverage close to the initial temperature for a reasonable amount of time
= fits nicely in my car's cup holder but, being as tall as it is, it may not be too stable in some of the shallower ones
- a sealing mechanism with several moving and hidden parts of which the on-off clicking button is visible at the top can not be cleaned easily and, if your coffee has milk-cream some very unpleasant deposits can accumulate inside
- the junction between the plastic upper ring and the steel bottom makes cleaning the inside difficult as well - the top plastic band is narrower than the steel lower body, meaning that there is an interior 'ledge' that had to be carefully cleaned or residue will accumulate

The big negative on this mug is what was supposed to distinguish it from 'the rest' - the top with its on/off seal button assembly. This makes the OXO not my 'first pick' whenever I have a choice of mugs. The only time I pick the OXO is when I forget to clean the Thermos the previous night (and the Thermos is very easy to clean) but, knowing what COULD reside under that on/off button seems to subtract from my coffee-drinking enjoyment.

If I was going to buy myself a third coffee mug, it would not be an OXO. I understand that it is POSSIBLE to clean the OXO very thoroughly but the cleaning is difficult and, for as long as there are better alternatives, most of us are likely to pick the better alternatives.

The OXO loses 2 stars because of the cleaning inconvenience, it keeps 3 because it does not spill and it keeps the coffee warm for a reasonably long time.
Summary: Hard to clean top prevents it from becoming my favorite mug

Content: First, I bought a red mug for myself. Later, a grey one for my husband. We loved the size, the good seal, and the sturdyness of the mugs. We made our own lattes here at home.

It appeared to be like heaven. We cleaned them by rinsing them (including lid) right after emptying them, and also putting them through the dishwasher each night.

Until the other day my husband said he was drinking his coffee and found a "chunk" come out of it. He was disgusted. So I set about cleaning the little buggers...

And there is no way in hell I could EVER take another drink from either of them, or buy another one of these mugs. I used some pipe cleaners and a good pull on the plunger to get up into the lid to clean it out...

OMG, it was the most disgusting thing. I seriously almost fainted when I realized WE WERE DRINKING OUT OF THIS THING.

Oh. My. God.

So I came to Amazon to order new mugs for us -- and happened to look this up and see that we are NOT the only people to have this problem!

Summary: Love gone wrong.

Content: I wanted a spill-proof, insulated container for getting coffee in the morning. This product came well reviewed, so I decided to give it a shot.

This mug was exactly what I was looking for. When sealed, coffee doesn't escape at all - I can shake the mug to mix sugar and cream into the coffee.

The insulation works very well - several hours after filling, the coffee is still hot enough to enjoy.

Finally, I haven't had any issues with cleaning the mug or liquids being trapped inside. I wish this was machine washable, but it cleans easily enough that it isn't a big deal.
Summary: Excellent Product

Content: The idea for this mug is good, but like so many others have said it just can't be cleaned. It keeps beverages hot, the seal works great and is convenient, and the mug looks great. But the fatal flaw is that the top can't be cleaned.

I purchased this mug thinking that all of the people saying the mug couldn't be cleaned were just doing it wrong, but that's just not the case. It is practically impossible to clean the top of this mug well. I cleaned with boiling water and soap for a good 10 minutes and I could still smell coffee odors coming from the inside of the top. Those odors would later impart flavor into the drinks I was consuming from the mug; so I just ended up not using the mug anymore.

If OXO could design a mug where the inside of the top could be cleaned this product would be a definite 5 stars.

Maybe a separate threaded cap on the bottom of the top to expose the inner area?
Summary: Great Mug, But It Can't Be Cleaned!

Content: I bought this mug a couple of weeks ago and have been really pleased with it. I have finally found a mug that does not spill and that retains the heat for several hours, as advertised. I highly recommend this mug!!
Summary: Great mug... finally!
