Although magazine reviews are generally restricted to either the wares that manufacturers will supply for free, or the products of companies buying significant advertising, they are not entirely worthless. I do believe that objective data, like field of view on masks, is probably legitimate.
However, in the six years I have been reading such articles, I can only think of one or two products that were reviewed that would have had an ice cube's chance of ending up in my gear locker. The real spectrum of available dive products is not represented by these reviews at all.
