Cute, but not useful for me.
If you drink mad Turkish or Cuban rocket fuel out of a thimble (I've seen it done! This stuff melts holes in police cruisers! These people are MAD I tell you!) then this cup is perfect for you. Perfect, I tell you. But, if you want to make coffee that sane people drink, these are not the cups for you. I'd also like to mention that Mega China is just the best bunch of folks to deal with. I've never had a single problem with any of the dozens of orders I've had with them.
