This system cuts with millimeter precision. It glides effortlessly along the rail, and the result from the top side is without material splintering; from the bottom side there are barely noticeable marks. I recommend it with my eyes closed to anyone interested in highly professional work. The blade it comes with is 48T; if someone wants a perfect finish, they should use 60T or more.

I have had the tool for six months. I haven't used it many times, but I have been impressed with it. It leaves a fantastic finish on the cut that even large professional miter saws cannot achieve. It cuts with excellent precision and vertically without any deviation. The use of a guide rail is necessary for completely straight cuts. It has a very good grip, sturdy construction, and excellent build quality. It has many settings that are not tiring or difficult to adjust, and they increase the tool's flexibility. I highly recommend it. It is one of Dewalt's very good tools. It would be good to also purchase the other accessories besides the guide rail, as they are sometimes necessary and not secondary.

The only thing that might give you a little trouble is the first cut where the excess rubber of the guide rail starts, in terms of starting to cut from the beginning of the rubber. There, you will need to use an angled guide to guide the circular saw from the beginning, as at the start, in order to cut from the beginning of the rubber, the entire circular saw does not rest on the guide rail, and the guide will initially guide it until the entire sole rests on the guide rail.
