Good for you, Muse.
I especially appreciate folks who let me know what they paid, where you can get it for less, or the vendor they purchased from. And of course anyone who uploads pics - so I don't have to rely on tiny glamor photos from just the right angle for my assessment.
I've been known to revisit products I purchased a while ago and pore over the reviews - just to see how perceptive reviewers are and whether I can trust them.
Consolidating reviews on similar items boosts the star ratings and creates an illusion of popularity. This is why Amazon does it. At times it actually makes sense to consolidate though. But, if they are going to consolidate, Amazon needs to make it easy for the reader to isolate. The buyer interested in the "Mineral Springs" candle shouldn't have to wade through reviews for "Pumpkin Pie," "Oatmeal Cookie," "Nutmeg Spice," "Cranberry Spice," "Pumpkin Pecan Waffle," "Pumpkin Spice," "Vanilla," and so on. Ridiculous. Where's that filter?
