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.
Awesome product. Buy the large one even for medium projects unless you are welding really small stuff. Was worried about reviews about the magnet being weak but mine wasn't. I don't know if they responded and added a more powerful magnet or it was a quality issue with others. Mine was worth the money and am really happy with the product.
