Great for small jobs where I don't have a plug-in handy and don't want to drag a cord to the job site.

Very surprised how long one 18V XRP battery lasts.

The saw arrived within a week, in perfect condition and I have been framing in a bathroom with it all day. It is a great tool and it almost keeps up with my mag77 only I don't need to roll out any cord's.

PLEASE NOTE: this saw has recieved some undue bad ratings because it is a BARE TOOL (a perfect replacement or addition to your existing 18v DeWalt tool collection) It does not come with a battery or charger ... well duh! A single battery retails for over $80 alone, what do you expect? It does however come with a blade (nice little suprise to me).

This is a great buy and I'm sure you will be very pleased with it's capabilities if you purchase one.

I thought i was just picking up a trim saw when i bought this 3 years ago.
Apparently i was wrong. I am a handyman/carpenter by trade and have used this thing to rip 1x and plywood, crosscut 2x anything...and it takes it. I keep 3 different blades and always try to use the appropriate one for the material i am cutting and of course, a fully charged battery.
The last framing job i did, i used this thing to cut over 250 2x4's for the walls. The corded Makita sat unused for two days.
For all the criticism of this saw, it does the job for me...for 3 years now of daily and sometimes abusive use.
But, as always, the Dewalt batteries suck so i keep 3-4 charged all day.

At the current time, cordless saws have noticeably less power than corded tools. The DeWalt DC390 is no exception to this. It will certainly cut 2" thick fir and pine lumber, but you won't get the same rate of production as with a corded saw.

This saw has a thick base plate, which I like. Thinner stamped metal base plates on circular saws often get bent after several years of use and the saws never work well after this happens.

A routine use of the DeWalt DC390 will be to cut thin stock such as plywood. It's handy to have a cordless tool for this purpose since you often have to extend your reach to make cuts. However, this saw is poorly balanced for such work. With the cut depth set shallow, the battery is raised high and the saw is top heavy. If you put the saw down as you would a normal circular saw, it will tip over. The lower half of the saw guard is made of a slightly flexible plastic. Given this saw is likely to tip off worktables frequently, I think this is better than having a metal guard which might get permanently bent. Plywood is often cut using a guide such as a bar of metal clamped to the work. It is difficult to cut with the DeWalt DC390 while keeping it snug to a guide because, in addition to the trigger, the saw has a safety that must be pressed with your thumb. It prevents you from wrapping your thumb around the handle, so you don't have a normal grip. (The DC390 also suffers from a weakness of all direct drive circular saws in that the motor leaves little clearance under it and tends to bump into any clamps that you use to hold the guide. It seems to me that manufacturers could do a better job of designing a motor housing that provided more clearance, even if only when the saw is set to do shallow cuts and motor is raised relatively high.

I bought this "Bare-Tool", as I already own another DeWalt tool and have spare batteries and a charger. I have a 18 volt "Black & Decker Firestorm" saw of this type, but it is very under powered, and the battery packs do not last well. This DeWalt will out saw the B & D numerous times over and is an excellent buy.

This saw got poor reviews due it being the saw only- which is great for those of us who have other dewalt tools and all ready have batteries. Otherwise it is a fine saw for use when pulling out a corded saw is too much work or your not near electricity. It's not a replacement for a corded tool- but it has worked very well for me when cutting conduit, some 2X4's and working on the fenceline without electricity.

I was kind of worried on whether the lithium ion batteries would fit and be strong enough to power this saw.
I own a compact 18v drill which uses lion batteries but there only 2.4 compacts,but I figured at worst case id have to buy
a 3.0 Ni cad battery,well I received it and dropped a battery in it and it fired right up so i am well pleased.

Now for the saw,It is perfect size for my small shop and very light to use,I love that i don't need to bring out extension cords to use.
Its half the rpm of a corded saw But if you let it do the work and don't force it it works well,I cut maple,oak and purple heart and it does all i ask.
Get a good blade,I use Diablo 40 tooth and it works well and leaves a smooth finish.
all in all I would recommended this saw to anyone needing a light small saw for versatility that can do pretty much anything you can imagine.
If you purchased the new lion batteries in a kit they will work with this saw saving a lot of cash,you can also purchase the 18v 3.0 Nicad battery
and the lion charger will charge it.
My next purchase is going to be the 18v jig saw so i can expand my cordless tools.

I used this saw this past weekend to cut deck boards and 2x4's. It is very easy to use and cuts great. I love that there is not cords to get in the way! The battery lasted for my entire project.
