I like to know all the functions, and how it performs. also I like to know how it worked out for the reviewer. with a vibe review I like to know where the motor /bullet is located, and in the videos I like to see/hear how the vibe dances around on a hard surface.
Pictures, a description on if it's buzzy or rumbly, the volume, if it's waterproof, and then experience. If I'm reading all 20 reviews on something I want to buy, I usually just skip right to the experience to see what they personally thought of it.
When there's only 2 reviews all of it is important, so I guess it depends on how many there are what parts of the review I find the most valuable.
It really depends on the item that's being reviewed...I know how to "use" lingerie, so I don't really need an instruction manual there, but pictures are always nice, especially on the plus sized items because those are always so hard to gauge if they'll fit my frame or not! But, I also don't really need a photo of a cock ring around a dildo...I can imagine what that may or may not look like without a graphic image! The "how well it performed" is what I really want to know...did it snap on the first use? How long did the batteries last?
Overall, it really just needs to provide most if not all the info that is pertinent to the item being discussed...continuing with my cock ring example, it does me no good to read a review that really only talks about your sexcapade and doesn't touch on how much it can/will stretch or whether the vibrators batteries died after only 10 minutes or if they were going strong an hour later (assuming the cock ring has a vibe...the last few I've gotten have had them)!
Quality is probably the most important for me. You can list the measurements, the materials, and the functions, but they mean nothing to me if it is not a quality product that is not going to break after 3 uses.
I'm most interested in the functions, performance and like to hear about specific experiences when using toys. I don't care for all the safety, packaging type stuff once you are familiarized with all that. I actually think the extended reviews could be reorganized better. Use/experience/perform ance kind of overlap too much. I find myself repeating things in my own reviews as a result.
Photos are nice too to get a better idea of actual size.
