They assisted in the scoping of the work, they located a lab that could provide the quickest turnaround time and liaised with the lab to help define our expectations. Name Your Test Price response to questions was extremely quick and their insight on laboratory procedures was excellent. I plan to use Name Your Test Price again in the future."

"I was searching for labs in the States who tested consumer products. I was unsure of where to go and how to get started. So many labs! The field was vast and overwhelming. I spoke to and they understood what I needed and made excellent suggestions and provided me with helpful contacts. Thanks Name Your Test Price!"

-Maggie Gilmour, Researcher, Discovery Channel - Toronto Ontario

"When we had a need to conduct some external testing, we started by contacting local testing labs and got quotes of $500 per sample. Then we found testing partners and they were able to get the job done for $200 per sample, saving us thousands! We have been working with them for our external testing and certification needs ever since."
