Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t 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 analyzed reviews to verify trustworthiness.
It’s a great idea, but the clutch mechanism is not well designed. If you make the gearbox case too loose, the clutch will engage and there will be no movement and a clicking sound. If you tighten the gearbox case, the legs will move for short time, but then stop due to too much friction. After hours of trying, I could not find a happy medium. All of my shafts and gears turn easily by hand. The problem is the clutch spring.
