You can say that again. I recently bought a kitchen knife with Amazon Prime that had ~100 reviews, an average of 5 stars. It cost £33, so wasn't particularly cheap. Just after I bought it the seller sent me one of those nagging emails asking for a review which I ignored. A week after they sent me another email, a copy of the first one. By the time I've already used the knife and found out it wasn't very sharp (my >5 year old knife of a different brand was still sharper), so I thought "be careful what you ask for, 'cause you may get it" and gave them an honest 3 star review. Not even 2 hours later I get an email from their rep apologizing for a "faulty item" and offering either send me another one or issue a refund and I can keep the knife in both cases. I realized what was the catch, but opted for a refund and removed my review when they asked me on the next email (obviously). So now this knife is still sold on Amazon, with 100 reviews and counting, only one 4 star review and the rest of them 5 stars.
