202 customers mention181 positive21 negative

Customers like the performance of the saw. They say it handles well, is easy to use and adjust, and works well for casual cutting. It's a lightly-powered saw that works well, but it's not like a corded saw. It works great for casual cuts in stuff like plywood, but any think cuts. It worked great cutting through 2x4's, 2x10's and 2x12's without an issue, and is carbide tipped and works on soft wood. It has worked out great, small jobs far from an outlet.

"This is a charm, cuts well, handles great. Too bad I didn’t purchase it earlier, light weight, easy to handle. GREAT SAW !" Read more

"...For a battery powered saw, it worked really well!! Almost beyond belief. Not having to worry with a cord does have some advantages...." Read more

"...Saw works great, needed it for a few different projects and it’s nice when I have to cut lumber to size to fit into the back of my vehicle...." Read more

"Delivered on time and works excellent" Read more

"Ok, the took is exactly what I was looking for, cordless, had enough power, cuts nicely but... It feels like a toy in your hand, really light weight..." Read more

"...Tons of power, decent battery life. Very nice cuts. The weight is good. All around a great tool!" Read more

112 customers mention104 positive8 negative

Customers find the corded saw easy to use. They mention it's safer, and easier to control. It's also easier to work on a ladder, and is an excellent time saver. The brake on the saw is also a big plus. Overall, customers find the product to be handy and powerful.

"...This makes it safer, and easier to control.Blade choice is important!..." Read more

"...Which makes it lighter and easier to use...." Read more

"...Too bad I didn’t purchase it earlier, light weight, easy to handle. GREAT SAW !" Read more

78 customers mention64 positive14 negative

Customers like the cutting power of the saw. They say it is perfect for quick cuts and great for light duty or smaller jobs. It is easy to use and great to cut sub-floor, stringers, 2x4's and much more. The 20V Flex battery gives it great cutting power with pretty long run time. Customers also mention that it cuts through wood smoothly and doesn't even skip a beat.

55 customers mention46 positive9 negative

Customers like the value of the saw. They say it's a good value for the price and that the handgrip is very comfortable. Some say that the bare tool is a real value.

"...Which makes it lighter and easier to use. It’s a good value for the price but make sure that it’s compatible with the rest of your Dewalt tools so..." Read more

Customers are mixed about the battery life of the saw. Some mention that it is powerful and will go a long way on a single battery, while others say that the batteries are underpowered and the saw puts a heavy load on the batteries.

"...This skill saw is powerful, and puts a heavy load on the batteries...." Read more

"...Things that I like are the power, decent on battery power time (with my 6AH batteries). Mostly easy to use. Well balanced...." Read more

"...The base battery is not included. Would recommend as large a battery pack as possible and multiple of you can help it...." Read more

"...IT IS AWESOME. CUTS FAST, DOESN'T BOG DOWN, QUICK, AND BATTERY PACK LAST HALF A DAY..." Read more

I really like this saw BUT.....
5 Stars
I really like this saw BUT.....
Overall I never give 5* on much & this is not quite worthy of 5 but it won't let me do 4.75 of 5 & the reason is the stupid safety switch to start the saw, instead of being like almost every other saw on the market, it is a slide instead of a direct push in. Otherwise it is light & well balanced even with a flexvolt battery.
