One critcism I have: if you give every yo-yo a positive review, then why bother reviewing at all? 
What would make someone really want to buy this yo-yo versus the hundreds of others they could choose from out there? What’s unique or special about this particular yo-yo?
I also agree strongly that there is a “moneymoon” aspect to reviews, where The New Thing© is interesting because it is new. You really want to hear from people after the shiny newness has worn off. Do you still pick up that yo-yo, 6 months later? Because that’s what it takes.
