It's worth bearing in mind that people who buy mid-range are also more likely to solidly review a working product than people who buy a high-end product; if I buy high end, I'm going to be a lot pickier, and likely more critical of the product. I wouldn't say it's necessarily an apples-to-apples comparison.
Or you would convince yourself that the widget is pretty awesome since, to be honest you paid a hefty price tag - which a sane person wouldn't do for a sub-par product?
There's a huge problem with user generated reviews in general that makes it very hard to go by top rating. Some peple will give 5 stars to a mediocre product, some will give 2 stars for a perfect product just because they wish it was something else (example: the # of people complaining that the Breville is made of plastic, at least the us verson gets that complaint a lot). At the last office I worked at we had the Breville kettle for a few years. Everyone in the office drank tea, so it was in use nonstop. It lated longer there than I did. I'd say it performed admirably, and if I was going to buy a plastic kettle in that range, I'd buy that one. I'd rather not be boiling water in a plastic container, but I'm not going to reduce the rating for it, unfortunately many other people will, so stars don't necessicarily have a strong correlation to quality/durability.
Considering how much tea I drink, I would have been most disappointed to discover price doesn't always correlate perfectly with quality ;-D
Otherwise I like the site; it fulfills that "family member asking for advice on electronics" niche well.
