Query: I love it!

A week ago I was of the mind that a coffee mug is a coffee mug. I've been using the same dinky, plastic one for years and haven't really given it much thought. I recently purchased this one on a whim and am awe-stricken at the difference. The auto-sealing mechanism is smooth - I don't even have to think about it while I'm drinking from it. Due to the seal my coffee stays warm much longer and I don't end up tossing the last bit. It's also nice and stylish hanging out on my desk. It's also nice and solid - I don't expect to have to purchase another one ever, especially anytime soon. I'm loving this purchase.
