My track saw is a DeWalt, the blades are 6.5 inches, 165mm, with a 20mm arbor - same as Makita. I saw the same review and others by the same group. I consider them OK, not great. They use a lot of subjective criteria. But their point about limited clearance for my hand on the DeWalt is something I would check out before buying one. But with three DeWalt tracks, there is nothing about the other saws that could cause me to start over. I like the review, it is a good way to get some information on a variety of saws it would be hard to otherwise get the same information about. But I don't think the DeWalt cordless is a bad saw just because they rated it the worst.
