ConsumerLab.com review: Usefulness of their reviews

Though I think that Consumer Labs does a good job testing various products I'm not sure how useful the reviews are. After reading a review on chocolate bars I started eating Ghirardelli® Intense Dark 72% Cacao Dark bars because it was a "top pick". After reading their latest review this bar is now rated as "not approved".

So that's not very useful when a tested product can go from great to bad in between reviews. I have a 2 year subscription and will probably not renew when it's expired.
