If you pull the unit apart you will find that the big parts that are hand soldered all have dull convex shaped solder droplets (cold-solder joints). something didn?t get charged. My hand was cramping after about 4 hours of gameplay due to its awkward shape. 4 of the long 35x17cm panels were missing in order to complete 16 cubicles. These slippers are beautiful and made very well. Other than the stones being very small and the silver chains were missing everything else was ok. I wore them 3 days in a row when I got them. In fact, I was so impressed with the first one which I purchased, that I sprung for a second one. I hate when stuff doesn?t fit. The box came and everything felt "loose" inside.
