If their specs are correct, overclocked to 400MHz (and cooled very well!) will produce 9M hash, or about .16 dash per day at current difficulty.
ROI in about 110 days if diff stays in the same ranges (doubtful. will probably be double or triple that depending on how many come online.)
(each stick represents about 0.01385% of the current total network hash)
I'd grab a couple for $39...... lol take my money please! Where to order?
