I write reviews all the time, and to be honest, Amazon makes it pretty easy. Basically if it shipped on time or earlier and was exactly what I expected, I will write a review and say exactly that.
I'm not trying to be negative but I don't see what value the type of review you say you are writing adds.
It's just a dinky review, you're not supposed to do a full product breakdown. If everyone thought of amazon reviews this way and just gave 30 seconds for a review for every item, then there would be no automated review problem.
