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 analyses reviews to verify trustworthiness.
This seemed to be a good value unit. It seemed to be made fairly well, although likely not good for continuous everyday use, more for occasional I would say. I did return the unit, only because I released after purchase that the clamp-meter was only for AC current, not DC (I somehow missed this fact as indicated in the product description). As I needed it primarily to use with our car (12V system), this made it unsuitable. Either way, seemed like a nice product.
