6 -1/2 in. Dewalt Saw 18 volt power
Good tool and well balanced; however, for work away from an AC power source a second battery is needed. I suggest that a second battery option be included when purchasing the kit.

Nice Second Saw
Have owned this saw for several years in conjunction with other Dewalt XRP 18V items which are slowly getting outdated. Have already had 4 of the batteries rebuilt once. Even when the batteries were new I found it lacking in power and run time. Always have to opt for my Makita worm drive for serious construction carpentry. Good for multiple 1 by sticks or thin sheet cuts, but not for heavy work. Planning on an upgrade very soon to something with a Li-ion battery and brushless motor. Given what's on the market today I would not recommend this unless it is for a beginner with small jobs to do and doesn't mind changing batteries fairly often.

Great tool!
Pretty powerful for a battery operated tool. Quick & easy to use. I love that you don't have to drag out a cord & find an outlet. I had a small battery op'd saw years ago (not to useful) but this saw is almost equal in usability to a full-size 7 1/4" corded saw. Works great!

This is a good value
For what I intended this tool for, it does work well. I wanted something light and effortless for smaller jobs or that quick cut that didn't require a saw with an extension cord. It's not as powerful as some, perhaps. But I'd bet this will get it done for more than half the jobs you wanted a that corded circular saw to do in the first place.

This saw makes the cut!
This isn't the lightest cordless saw available, but the DeWalt DC390 is no lightweight on power, either. The run time on the 18v XRP battery is excellent, and like most DeWalt cordless products, this saw is made to be used!

In addition to outstanding power and run time, depth adjustments are easy, and vibration and arbor runout are low. This is a well-made saw that should last for many years.

My only complaint (and this is a very minor one) is that the spring in the power switch safety lock is a bit stiff. After all, SOMETHING has to be less than perfect! On the other hand -- literally -- since I am left-handed, the double-sided safety lock is a bonus.

This is one tool that gets an entheusiastic two thumbs up!

Light on its Feet
After I got used to the blade being on the left, I really liked this saw. It is very easy to adjust, and light for use in difficult positions, but with plenty of power. My only beef with it is the double safety trigger is a little "too safe" and awkward to use. Something that I really like about this saw, is that the charger and the charger cord fit easily in the case.

love this little saw
I really like this saw. I use it for small project and quick cutting tasks where you dont want to use a table saw or drag out other saws and cords. The battery life is short but what would you expect from a cordless saw. It wasnt meant to be a heavy all day use saw. As long as you understand that you will love this little saw for small quick jobs.
