The review hijacking as covered in a recent consumer reports article [0] really makes me doubt any item with a significant number of reviews. I have seen similar myself and Amazon's excuse for it happening should not be accepted and probably requires intervention, they are in effect support false advertising and while I have not seen it myself I have seen people claim it occurs on amazon branded products too.

it is just not acceptable a shopping site has so little product integrity that they cannot guarantee a review belongs to the product it is attached too. Amazon could fix a lot of this by assigning each product a unique number that can never be reused; as in ever. Let the retailer point back to the previous version if review history is important but never let it appear as review of the viewed product
