I've given my issue thermal mug to the Mrs as I never use it and she has a long commute. She came back to me and asked how the hell you drink out of it... I must admit it's got me stumped too. It's the one made by aladdin, black plastic outer and a stainless steel inner. It has 2 lids, the top one comes off revealing a small chamber where on most other mugs you have a hole where the drink comes through into the chamber in order for you to sup. Trouble is, there isn't really a hole to drink from, just a small pinhole which p*sses steam into the chamber which in turn leaks out the top cover. The only way to drink is to remove both lids, and that kind of misses the point. Am I missing something? Or is it just a horribly gash bit of kit? Any suggestions for a better replacement are very welcome by the way.
