I love the idea, I do. But there's a lot of logistics and questions involved. Who gets to hold the funds, and are they trustworthy. How is it decided what product gets tested. What happens If half the group disagrees with a decision, and refuses to send money.
I know not everyone has extra money to send their own blind sample in, considering shipping is 120 plus up to 200 alone. But over the years, i prefer to use sources who openly have a credit or reimbursement policy. While this is no guarantee of a product being 100% accurate, at least I know I will get something in return for the money I spent. A bonus is if the source has covered or offered in the past to cover testing when a customer has a serious concern with one of their products.
While I'd love to see one get up and running, I'd prefer to not get involved and send blind samples in myself. Lots of potential headaches to work thru with a group.
