I also purchased these on deal day for really cheap (I don't recall the exact price).  Here are the positives: they were cheap and they are big.  That's about all I can say positive.  And honestly, I think they may be too big, they look a little silly to me.  So maybe the "big" thing isn't so much a positive.  But hey, to each their own I guess.

I found the stones to be cloudy and unclear.  Really just no "wow" factor at all.  They were not bad enough for me to return, but certainly, if I had the choice to purchase them after seeing them, I would have passed.  Even at the lightning deal price.
