I recently ordered a dozen things from Amazon from six vendors. All
the things were pretty technical – ethernet switches, fiber optic
cables, transceivers, things like that. This is normal.
Four of the six vendors asked me to review their products. Two asked
me multiple times over the same order.
Here’s my policy, and I urge you to consider the same one:
I will only leave a review on a commerce site if I have an unusual
experience to report. An unusual experience is either surprisingly good
or exceptionally bad. I won’t give any feedback for a transaction in
which I paid the agreed amount of money, received the product in a
reasonable time, and the product worked as expected.
Adding reviews outside of that policy has two negative effects: it
adds useless noise to the review section, and it tends to inflate
star-system grades.
