Best price
I have had a Dewalt impact driver for Many Years, a 12 volt then a 20 volt, my 20 volt stopped working in middle of job, Amazon delivered a replacement next day , love this tool has lots of power, I tried my 12 volt overnight, it is weak compared to the 20 volt

No clip
The quality is good, but every picture shows the clip for a tool belt and it doesn't actually come with it. Very miss leading so now I have to order one.
