Not good on 18v. Very poor performance, test was on 18v. Need 24v LiI. I have these maxselect tools and you need the 24v battery .

The Ridgid was a low performer, with last place in speed by a wide margin and last in duration results. It also tied for second heaviest, not scoring many ergonomic points. The grip isn't too wide, but the tool is among the largest overall. This driver really heated up during testing, making it difficult to remove the bit from the tool. It also seemed noticeably louder than others. No belt hook. Light over trigger.
**Nice price but......
**24/18V great concept but not a great impact driver
**Need to inquire about LLSA bc purchased from non-HD
**Latest versions of Ridgid 18V impact drivers are more compact, lighter with similar or more power
**24V batteries are unavailable at B+M HD
