The only thing I am concerned with is that they are drilled correctly, and I have no reason at the moment to doubt that they are.
The seller has great ebay ratings, and they have a 7 day return policy, so I don't imagine too much trouble should there be any problem.
They should be here within a week, I will report back as to their "performance in the field"
The two I purchased were very unique, struck me immediately and had prices I just couldn't resist - hardly seems fair to tempt a PAD sufferer in such a way...
Some are as low as $35 I think - with lots of nice ones around $60 and some real spectacular ones over $120 - certainly one in 10 is severely underpriced in my opinion (which counts for very little in this area unfortunately as I am new to the sport)
