I've been consistently watching the Amazon website to read the latest reviews on the 54 inch 5.1 Vizio. Up until yesterday there were about 17 or 18 reviews in total, most of them very positive.
Yesterday Amazon did something which surprised me... they folded the reviews for the 42 inch soundbar (a completely different soundbar sonically, and in terms of drivers used) with those for the 54 inch model. So today, unless you read the reviews carefully, particularly the user's heading for their review, you will think there are 768 reviews for the 54 inch soundbar.
Looking at 768 reviews, overwhelmingly positive, you might be inclined to buy the 54 inch without a critical look, based on a false statistic. I am convinced, without hearing it yet, that the 54 inch fills a unique niche, and is a very good product, but this review practice, if not unintentional, is not a good precedent.
I lodged a complaint with Amazon yesterday, and maybe it takes some time for them to correct this. But it really is not helpful to the consumer to not know that he may be reading and assessing an inappropriate review.
