It would be nice to be able click on the bar graph and for it to filter just the reviews for that rating, like Trustpilot does.
This is unlikely to ever change. People want different things from a sex toy review so there is no universal good way to write a review; some people want the ins and outs of the product, some want to know how the person added it into their sex life, some just want the reassurance that other people have bought the toy and liked it, to name but a few reasons. People will also write reviews for their own reasons be that to be informative and helpful, just to share their opinion, because they were bored when the LH email came through asking for a review or something else entirely.
The only thing I can suggest for this is when you find reviews that you like, look up the person’s member profile (which isn’t as easy as it used to be I’ll admit) and have a read through their reviews. Make yourself a little list of preferred reviewers, ones that tend to answer the questions you want answered and/or those that have similar opinions to yourself/like the same toys you do. It’s not a perfect solution but it might help a bit.
