I imagine everyone witnesses this problem... If you do then please support this idea.
VERSION 2 OF THIS IDEA FOLLOWS...
Customers hastily write product reviews in the service section. Then when they realise their mistake they either express their annoyance in the product section or they just write the same thing.
Here are some suggested solutions - all would help.
1) Allow the merchant to choose which of these the customers is asked first: products or service
2) Allow the merchant to edit every review that comes in on an individual basis: OPTION: Publish my customer's Product review first
3) The customer will arrive at the first form all set and primed to type in their best words. If their head is full of words about the Product then forcing them to write about the Service stands to unhinge that train of thought. Therefore I strongly recommend the headline field should be positioned at the very beginning of the form. Being generic they can write a headline about the product or the service, or a mix. Currently the headline is a sub section of the Service section. That is wrong.
4) Use cleverer wording so the customer gets the message better. At the moment it might seem good, but it does not work. I've got simplified suggestions for this as a starting point, which I would class mobile friendly, using even fewer words than now.
