Do you trust user reviews when you are researching products to buy? or hotels, hairdressers, etc?
My husband thinks they are more reliable than things like Consumer Reports because of the chance it will be uninfluenced. I don't know if I agree. I didn't have a lot of luck when researching new mattress and box springs, but I guess it also depends on if I am researching a product that has a more immediate result, good or bad. Sleeping on a mattress takes time to know if it works and when you finally know, you don't take time to report on it.
Unlike a food product, make-up, or Lipofuze diet pills; you either like it or get the desired results -- or you don't.
