Although we implement the QC process in-house, we believe that the third party product testing is crucial in that it provides unbiased information, making our customers rest assured to buy from us. And with a third party reviewing our products, we can find out anything that may have been missed. So that we can make some improvements and have peace of mind knowing that our products are safe to sell to the public.
