A seller will always know you have received your order by the absence of messages saying “where the feck is my order?!!”
Leaving “reviews” that review the delivery and not the product are frustrating for everybody else as we all want to know about the product! The number of times we see “10/10 arrived quickly, haven’t tried yet” is mind boggling!

Hi, I've taken the other point of view. If the order arrives in good time, looks, smells, weighs, feels ok, it's 10/10.

If there's something up with the product sure reflect that in the review otherwise you're preferences are subjective.

The key for me, especially starting new here was, will I get something in the post and not be ripped off.

Having said that, opinion reviews on the product pages are useful.

I dunno...I think we have a right to expect a paid item to turn up and be what we ordered. I’m confident that happens across LB 90%+ of the time which by your logic means 90%+ of reviews are 10/10 and totally meaningless IMO.
Obviously splitting a review between delivery/stealth/quality etc would be better but instead we have one overall rating. How can you rate something “overall” if you haven’t tried it?....why not just hold off on the review until you have? I do get that it’s subjective but with so many strains available here I want to know how people actually experience them....

Yes.

But the vendor doesn't know who's reviewing so if you need them to know, a message would be better.
