Mine was just delivered!
My wife called me to say the UPS guy dropped it off his handtruck twice, cursed the world and said he wished she wasn't home. I'm headed home to examine the damages (which are hopefully none, i've got dough a brewin!)
Edit: This thing is tough! With all the dropping going on (I guess he dropped it 3 times, not 2) the top compartment unseated itself and fell down causing some fibrament damage. The non fibrament aspects of the 2stone are unphased. I called up UPS and complained, they're going to contact me on monday to "schedule an inspection". sigh, maybe i'll fire it up anyway.
Here's the worst of the damage, on a top stone. The circular stone doesn't seem to be damaged at all, although Willard's insert mentions that you should be careful not to drop them in-case of hairline fractures that eventually go out of control.
