Review on Black Zojirushi Stainless Steel Travel Mug - 12 Oz/0.36L by Trevor French

I've been using mine for about 5 months now. It's fallen on the pavement a few times and the plastic rim has suffered superficial damage, but so far it's held up well to my abuse. The heat storage capacity is not bad, as said, it lasts for several hours. I bought a large Zojirushi thermos for non-coffee drinks (or ice water in summer) - the pods retain the flavor so keep that in mind. a leak. Liquid tends to get caught between the fancy seals and the cap, often resulting in a small amount of liquid spilling out when I unscrew the cap. It leaks less than the used thermos I've picked up, but it's still annoying. For the seals, be sure to check/clean under the "nipple". I found a strange bacterial growth there (my fault!) and since it's a bit difficult to clean it can be concerning.
