I’ve been a professional carpenter for 26 years and this saw is terrific. The key word here is “battery”. It is not a 15 amp worm drive skillsaw, and it will not completely replace your 110 volt tools. It is extreamly handy to use and capable of real work. In a skilled hand this tool will do a lot of work and not complain about it. Relax, cut straight, let the saw do the work. Highly recommended.

I purchased this saw about one year ago at a big box store. I was debating between this cordless model and one of the lighter duty DeWalt corded models. I selected this one figuring that it could be useful when on the roof or other location where cords would be a hazard or inconvenient.
The saw works well for light duty applications. I have used it easily on 2×4 and 2×6 materials, ripped 4×8 sheets of 3/4 plywood and cut lattice for a porch enclosure project. All done without problems. The battery lasts a lot longer than I expected; I typically can get through medium-sized jobs (say two to four hours for the project) without a recharge.
The blade included with the saw is easy to change and is fine for rough work. If I was framing a house, however, I would want a corded saw, but for a homeowner, there is no need to have anything but this saw.
I just don’t see any downside to owning this at all.

I got the DC390 as part of the DC6KITA package. From reading the reviews, I was skeptical about the power of the tool when cutting. I broke out a 2X4 and began testing the saw with a fresh battery and the supplied Dewalt 16T blade. Although you cannot force the tool through as in most of the sloppy framing I have seen, it does cut quite nicely and with respectable speed. It is a matter of just letting the tool do the job. Upon ripping down the 2X4, I purposefully went off line so I would have to twist the tool to compensate. I did not find that the saw binded or bogged down. It just kept the RPMs up and did it’s job. Is this going to replace a corded circular saw? NO. But for most little projects this tool will do it’s job fantastically.
To make sure that the tool will actually do it’s job acturately, I measured everything with my Starrett Machinist Square and it is true 0 and 45 drgrees. The shown measurements are correct and the depth settings worked well.
I rate this at 5 stars because I went into this tool knowing it was not a corded tool. The battery life seems adequate and the portability over the corded is a great bonus.
