"I loved my last toaster - it was the best toaster I'd EVER used, it was absolutely perfect in every way, and I was so sad when it finally gave up the ghost after 20 years of sterling service. I thought that this one looked quite good as a replacement and I couldn't believe how low the price was, so I took a punt and bought it. Well, what can I say: the last one was amazing, but this one is, without a shadow of a doubt, ten times better even than that. I can't stress how perfect it is in every single way. Carling don't make toasters, but if they did.... etc. etc."
"Four Stars."
So how could it possibly have earned the fifth star, then? Are you bitterly disappointed because it didn't sprout little legs, take a jaunty walk to your local bank branch, open its little toastie-pocket wallet and pay your mortgage off in full for you?!
Anyway, five stars is meant to be the norm and the starting expectation and a product should only lose stars for shortcomings. Anything less than five stars means that there's room for improvement - which doesn't seem to be the case here at all, going on your glowing review.
And as for the people who don't realise how the stars work and somehow seem to think that, defying all innate simple logic, one star means the best....
"Sooo, sooo glad I bought this - it does everything I wanted and more and I could not be more thrilled by it. One star."
Did they watch THAT infamous episode of Going Live, listen to the caller's somewhat negative 'review' of the band Five Star, put two and two together and assume that the band had chosen their name owing to their unanimous belief (not to mention unscrupulous honesty) that they were really rubbish?!
It's amusing in a way, but I feel very sorry for some of the smaller Marketplace sellers and suppliers who work hard to develop and select excellent products so that they can earn an honest living delighting their customers with top quality at very reasonable prices - and then, because of clowns like this, they get shunted right down the listings and, even if people do actually see their item in the listings, most will see the rating and scroll swiftly on by without bothering to click to look any further.
