In summary, once used on a 20-amp breaker circuit this puller is a reliable and efficient tool for removing dents. Its build quality isn’t the best but its good enough. It has a versatile arsenal of attachment options that make it a valuable asset for all types of panel pulling. (I personally like the O washers with the claw on the puller) Overall, it's a worthy investment for anyone seeking an effective and user-friendly dent removal solution.
