Excellent product for an excellent price
I use this product on a daily basis. As a marine mechanic I use this for engines as well as repair on some of the fixtures on the boat. Dewalt has always made a reliable product. Been using Dewalt tools for over 30 years.

i will buy again
we install industrial equipment impacts are priceless, but the DeWalts seem to spend a lot of time in the shop. Looking at replacing them with another brand. We use DeWalt because all the crews have the same equipment and it's easier when multible crews are on the same job and can share batteries and chargers. But that doesn't matter when even the new ones are at the service center for repair

Professional technician approved!
I use this tool all day long, Surprisingly strong, super convenient. No air hoses dragging inside cars. Batteries last too! I love this thing!

Easy To Use
Handiest impact in the box
I have 2 of the 1/4 in hex drive impacts and use an adapter with them. This 3/8 sq dr. has a better feel to it and I know that is is getting bolts tight. It is great for access panels, and anything you would use a 3/8 dr. socket for. No cord is one of the best feelings. Even with the heavy battery it is lighter than an air impact with a hose. It has enough power for 3/8 use.

Love this tool
I work on cars all day and this tool is great. Be careful, it will twist off 1/4" and 5/16" bolts.
