White Horse Laboratories Counterfeit Detection Report, Week 20

White Horse Laboratories Counterfeit Detection Report, Week 20Week 20 saw a moderate improvement in lot acceptance, edging up to 53.1% from Week 19′s appalling 45%. Lot pass rate for electrical testing edged up as well from 43% to 50% in Week 20.

Week 19 was the last for our previous poll question, “Are buyers more cautious in the past 4-6 months and rejecting lots for minor issues with growing frequency?” The response was clearly supporting that there has been a change in buyer awareness, with 67% agreeing with this position, and 33% agreeing rather emphatically.

Our new poll question, then, goes another step and asks, “Has the increase in buyer caution had a negative impact on sales and the market overall?”. Post your vote on this week’s poll at http://conta.cc/Of90yi.
