This product’s journey from last year’s mediocre performance to today’s standout capability demonstrates how much cordless 4-inch circular saw technology has improved. Having tested all four options hands-on, I can confidently say the Heimerdinger 4-Inch Cordless Mini Circular Saw & Angle blew me away with its versatility and power.
