For my two cents I agree with @Ian_Chimp , I don’t think adding additional reading would help and I’m not sure over simplifying it is a good thing.
I do think the addition of the video would be good as it breaks it up and does give the overview without the initial reading but honestly testing is a huge bonus and privilege, if people can’t manage to read through the guide then I’m not that hopeful that their review writing is going to be that great and informative. Obviously, people probably will miss or not fully take in a few details but that’s what the Sex Toy Tester - Chit-Chat is for.
I do think just having the link to the guide clearly posted everywhere is the most important thing.
