I wouldn't bother without a written policy, consistently observed. At least one of my product review posts was deleted, presumably mistaken for spam. I just liked the product, and paid for it myself.

I understand the mod chores and nature of the beast. I've been a mod on a couple of hobbyist sites for many years. But without a consistent policy, or a designated product review forum, it's usually a pain in the neck for everyone. It's too difficult to tell at a glance the difference between an enthusiastic review and spam. And if the post is deleted, it discourages posters from bothering again.

Nowadays I just write reviews for the vendor I bought from, Amazon, or my own YouTube or blog pages. When I'm looking for user feedback on a product I check Amazon first, then a few relevant discussion forums to get a balance of opinions. The problem with discussion forums is the usual digressions into arguing about stuff other people have posted, rather that sticking to the characteristics of the product itself.
