I have a small furniture store and this is the best laminate cutter I have found. Once you set it right, it will make the border almost file-free. I always carry a small Makita router with this attachment so I don't have to spend time configuring it through trial and error every time I want to use it. Definitely pays for itself and delivers a quality finish every time. It saves items and prolongs the life of the bit if you use the flush cutter to trim the bulk first and then use it to finish. Much more accurate than by hand.
