Yeah, the Zojirushi Stainless Steel Mug is meant to be leakproof. The manufacturer talks about its secure design, and our research backs this up. It's got a safety lock feature that helps keep leaks at bay.
However, there are some things to keep in mind if you want to make sure it stays leakproof. The mug itself isn't dishwasher-safe, although you can put the lid in the dishwasher. It's best to hand wash the mug, which helps keep it in good shape and looking nice. Because of its stainless steel and insulation, hot dishwasher cycles might mess with its durability.
Plus, its interior has a SlickSteel® finish that fights off stains and rust, so hand washing works well.
A good way to take care of the mug is by hand washing both the lid and the mug regularly. Using a bottle brush can help clean its narrow neck. This kind of regular cleaning keeps it working well, keeping drinks hot or cold for quite a while.
From what we've seen, people are pretty happy with how leakproof it is, as long as you're sealing it properly and keeping it clean. So, yeah, the mug does a great job at staying leakproof, just make sure you're taking care of it right.
That way, you'll keep enjoying its perks for a long time.
