Your phone call is answered by a real person. A person committed to service. James answers my questions and the small issues I am concerned with is timely addressed. The delivery time of orders is impeccable. I could not ask for better. Would not go any where else. Thank you PeakForce Labs.

Pricing is Great. I ve never had any delivery issues. Everything always ships right away and I have it within a few days. I ve been ordering from here for just under a year. I ve also recommended a lot of people come here to buy.

Great Company. Orders are filled almost instantly; and if there is a backlog on popular items, they are shipped promptly. Their points system makes it worthwhile to make repeated orders. Also, having all products tested/verified is reassuring.

Thank you, Ed! We work hard to fill orders quickly, so we're glad that shows. We're happy the points program is worthwhile for you, and third-party testing on every product is something we'll always stand behind. We appreciate your support!
