White Horse Laboratories Counterfeit Detection Report Week 23

White Horse Laboratories Counterfeit Detection Report Week 23We saw a bit of a relapse in Week 23 with quality ratings in both physical condition and electrical characteristics sagging to 70% and 61%, respectively, from Week 22′s 85% and 74%. Several outright counterfeit products lead the decline, but fortunately they were identified before getting to an end-user.

That leads us to our July poll question,

“Has the increase in buyer caution had a negative impact on sales and the market overall?”.
