I replaced all the windows in my house and bought this saw to use for trimming the windows inside and to install crown moulding. The first thing I did after setting up the saw was check the various miter cuts with an angle gauge. The saw was dead on right out of the box. After replacing the windows, I used the saw, with the blade installed backwards, to cut the vinyl siding I installed on my house. The saw performed flawlessly. I do agree with other reviewers that the dust collector doesn't work very well, but I connected my ShopVac to the saw and that took care of the problem. I own several Dewalt products, and all have lived up to my expectations. I would not hesitate to recommend this saw to anyone.
