    • Great tool
There is a lot of power in this small saw. Cut through plywood like butter. Very easy to handle, no kick-back.

    • Great tool!
This has become my go to saw for most of my work. Easy to handle and has plenty of power. Its just able to cut two by material and is very easy to manage on plywood cuts on walls for example since its so light. I agree its looks a little weird at first but I have grown to use my "axe"

I bought this saw about a year ago (it’s actually my first saw), and it’s been pretty powerful. Back when I got it, I saw some reviews saying that bigger batteries were necessary to get the most out of it. At first, I was using a 5Ah battery, and it worked fine for plywood, studs, and general wood cutting. Recently, though, I decided to push it a bit further and tried cutting granite(yes, an actual granite countertop). That’s when I realized the 5Ah battery wasn’t enough. You could feel the resistance, and the saw just didn’t have the power to go through it smoothly. So, I got an 8Ah battery, and wow, what a difference! With a bigger battery, the cuts were flawless, fast, powerful, and effortless, obviously using the proper blade. I was already happy with the saw for regular use, but this recent challenge made me want to finally write a review. If you’re planning to use it for heavier materials, definitely go for the bigger battery and right blade. Overall, really impressed and glad I bought it! ... show more

    • Just what I need when I need it. Works great.
This saw is a great tool to have especially when you need something for a quick job. Durable and made of good quality.

    • Two things I haven't seen on Youtube
Two things that I haven't seen on Youtube; (1) the shoe is held on by a rivet fore and a rivet aft. Even when the shoe angle is secured, the shoe has a bit of wiggle. The best use is for stairs, shelves, reducing long boards, or other cuts that don't require the bevel accuracy of a miter saw; (2) leave the handle and belt clip on - you can lay the saw down on the left side without the blade guard lever contacting the surface. ... show more

    • Dewalt tools are for women too.
This 4 inch circular saw has given me the freedom to make and fix projects multiple times. Being much lighter than a regular sized saw, it is functional, powerful, well built and fairly priced. I have used it to enclose cabinets, make shelving, make slates for my bed and plywood support for mattress. I can even cut thick boards by cutting part way and turning to cut the rest. The light is very helpful to increase accuracy. I have several Dewalt tools and prefer this brand. ... show more

One of the standout features of this saw is its ergonomic design, which allows for comfortable and controlled operation, reducing user fatigue during extended use.
