To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I was worried that the LMB and RLM wont have a at 'click' with it or it wont be pronounced enough, just like a touchpad on laptops. It has one and it feels like a nice combination of mouse and touchpad. Everithing else as in reviews :)
