Review: Zojirushi SM-KHE48 16-Oz (473ml) Stainless Steel Mug

Zojirushi 16oz


Whether you are commuting with your morning coffee, or having the coffee shop fill your mug, the Zojirushi 16-Oz Stainless Steel Mug is the Rolls Royce of  travel mugs. While it does not look very “muggy”, it fulfills the requirements for a travel mug in that it allows you to transport a beverage while keeping it hot (or cold), and allowing you to drink from the container one-handed without spilling. Not only that, but it is easy to clean and good looking. With 85%  5-star reviews on Amazon, it is a clear favorite.

Zojirushi 16oz open to drinkThe Zojirushi Travel Mug is actually a flask body with a wide neck and a fairly complex lid that screws down tight. This system has both benefits and disadvantages. The lid has a flip top that is easy to operate one-handed, and can be locked down to prevent spills. Once you flip up the lid, a spout makes it easy to drink directly from the flask. The lid consists of several pieces and have been criticized as “fiddly”, but they come apart without trouble and this makes the lid easy to clean. One issue that does crop up repeatedly is that the spring in the lid isn’t strong enough to hold it open and that can be irritating.

The interior of the Zojirushi Mug  is finished with a proprietary electro-polishing technique called SlickSteel instead of a non-stick coating. This offers superior corrosion and stain resistance by creating a super smooth surface along with all the hygiene benefits expected from stainless steel.

The claims regarding insulation are well supported by user experience. Hot coffee will stay hot for 6 hours and more and cold drinks, especially if they have ice in, stay cold for more than 12 hours. Thermal transfer is minimal and the flask does not even get warm when filled with hot liquid. There is also no condensation with cold liquids.

One last selling point  for the Zojirushi Stainless Steel Mug is that you have a choice of six colors and between 12-Ounce and 16-Ounce versions.

This product is highly recommend by everybody who uses it.

What buyers on Amazon are saying

-“Keeps my coffee warm for hours on end! I love the way the bottle is designed – sleek and elegant and slim. I also like how I can lock the flip top so it doesn’t spill coffee in my bag.”


Zojirushi 16oz ice blocks-“Had this mug for a week before the small, plastic hinges for the lid broke. I say this is a shame because it is otherwise THE BEST travel mug I have ever owned.”  (Remember: Amazon has a 30-day return/refund policy)


-“It does what it says it does – it keeps you beverages cold or hot for hours! Seriously hours! Ice cubes were still ice pieces 26 hours later. Keeps my coffee hot for at least 5-6 hours. Almost too hot at times. Fit and finish are top notch, ease of use and care- easy. You will need a bottle brush to clean it well though.”
