If you can't stand a lukewarm cup of coffee, reviewers say the Zojirushi Stainless Steel Mug is for you. The Zojirushi is the clear winner in experts' temperature-retention tests, keeping liquids hot or cold far longer than the competition. It's reported as almost completely leak-proof and easy to operate with one hand. But the price is high, and some owners wish for a more comfortable spout and a streamlined lid.
Excellent at retaining temperatures. Reviewers say the Zojirushi Stainless Steel Mug truly shines at keeping drinks piping hot or icy cold. After eight hours, the mug kept coffee 10 degrees hotter than the next-best mug in expert tests. Owner reviews are equally enthusiastic, with many saying the mug keeps drinks hot or cold through an entire workday with ease. The mug also earns praise for a truly leak-proof design, with superior seals and a secondary sliding-lid lock to head off any dribbles or spills, even when the mug is tossed in a bag. Reviewers say drinks retained their flavor and don't report problems with condensation. The mug is available in 12- and 16-ounce sizes.
Offers one-hand operation. The Zojirushi Stainless Steel Mug has a push-button lid that is easy to operate with one hand, experts and owners say. While most reviewers say the mug is comfortable to drink from, a few complain that the lid can poke their face; a couple of others say it can block their vision while driving. The mug is not dishwasher-safe, but experts say it's easy to completely disassemble and clean with soap and a bottle brush. Like all stainless-steel mugs, it is not microwave-safe. Most owners appreciate the mug's slim, easy-to-grip design, but some experts note that it may be too slim for a secure fit in some cup holders. It does not have a carry handle.
Built to last, but finish may scratch. Experts have no complaints about durability: The Zojirushi Stainless Steel Mug held up just as well as other stainless-steel competitors in tests, sustaining only minor scuffs after drops, they say. Owners are also pleased, with one reporting only a small scratch and no dings after a fall from the top of a moving car. A few complain that the finish could be more scuff resistant, while a couple of others say the rubber seals broke after normal use. Zojirushi backs the mug's vacuum insulation with a five-year warranty.
The Zojirushi Stainless Steel Mug blew away five other mugs in temperature-retention tests, and the reviewer lauds the leak-proof seals and durability. The mug is also praised for ease of use and cleaning. However, it is too thin for some cup holders, the reviewer notes.
