I saw those and considered bidding on them, but I think you need to make a definite highest bid in your mind. I wouldn't want to pay much for them myself, knowing that they may not work.
There is no guarantee that they will, you would probably find maybe one does.
I decided not to bid as I wouldn't want to spend more than $25-30 per box myself. (Maybe I'm a bit cheap, but I hate buying stuff that possibly doesn't work at all)
Its a risk you take I guess.
