Review: Great product - Absolutely love these. Easy to install and extremely sturdy. Can’t find anything close to this in stores.
Review: Great well made product. - This is a must-have tool. Very clever and well-thought-out design. It worked perfectly for cutting the opening for a light fixture and made the job quick and clean. The plastic guide pieces are especially smart—I only wish it were possible to order those separately and reuse the saw, because that would make this even better. Overall, this is a great product and absolutely worth it. Highly recommend.
