This reminds me when I was looking at the Daft Punk Tron headphones on Monster Cables site... They weren't even available yet, and there were two 5 star reviews... Both said essentially the same thing... "These look awesome, and they are produced by monster cables so they must sound good."
The exact reason i sort reviews low to high on every website. Its easy to impress someone who doesnt have a clue, but i want to see who is complaining about it and why.
I feel your pain though, i often write reviews and i know how it can get, you write a review revealing some serious flaws with a product then you have idiots going '5 STARSS!! omg these look proper amazin, i havent bought them yet but the description sounds like its really good....'
