What's their business model? A priori, I don't trust them because there's no reason for them to give out all that information for free. I assume it's a affiliate marketing / referral revenue stream? I suppose it could be fair within those parameters, but it would mean there's no incentive for them to test products that don't have such a program.
I pay for Consumer Reports, since you actually need a paid subscription to access the data, which makes sense structurally. I don't really know if the reviews are any good, though I've been relatively happy with it. I also paid a subscription for an independent supplement testing lab, but I forget what it's called at the moment.
Man, this comment is getting way more attention than I expected lol
Yes, they work on an affiliated model. From their About[0] page:
