For me the essence of the review is our person experience. I assume that people interested in a product have already read the specs; size, color, material, etc. I simply verify or clarify these details. Likewise, I could care less about packaging - they all come discretely boxed and I throw away what ever packaging they include.
So for me, I try to explain how well something worked for myself or more likely my partner. Adding details of why the design, size and features of the toy worked (or didn't) for us as a couple. I have to laugh when I read the 'Experience' part of reviews and they describe how easy it is to clean - really, who cares?
Sex toys are supposed to give you a great orgasm - in my opinion that's what people want to read about!
