Familiarity: I've used it several times
There is a design flaw with this mug. The sipping spout is flat so the excess coffee doesn't drain back into the mug. Eventually, the mug will get tipped backwards and the coffee will creep up under the latch and exit on the other side...where you can't see it...and it will get on you...probably on your way to work.
Don't get me wrong, the materials, finish, size, assembly/craftsmanship are excellent. I am now considering using a dremel to re-contour the spout to promote return draining. But, I should not have to do that with a new product, and I am concerned that even if I do it will mean I won't have a watertight seal when the latch is closed.
