Rated 4.2 out of 5 by 6 reviewers.
Rated 4.0 out of 5.0 by Newest model NO mar Newest model of dual trigger NO MAR pin nailers.. Works like it's supposed to do. Leaves the tiniest pin nail hole and if working with bare wood just wet the area and the swell will fill the hole leaving a perfect finish. No more bugger marks and a very professional look to the work. Be aware it has dual triggers and will fire when trigger activated even if not near anything at all... YES it is not wise to shoot pin nails across the room. This tool is meant for a skilled user in that respect. January 13, 2015
Rated 5.0 out of 5.0 by Sweet little pinner This pinner does what it supposed to do it. Very comfortable in the hand. Very well constructed with almost all parts being metal versus plastic. A joy to use. June 7, 2014
Rated 5.0 out of 5.0 by Great Gun Best 23 Gauge for the price. I Like it better than the old Omer April 1, 2014
Rated 5.0 out of 5.0 by Sweet Tool This nailer works excellent.  Nice size and comfortable.  A must for cabinetry, moulding, and trim.  Love the accuracy and smooth operation.  Very easy to load different size nails. December 18, 2013
Rated 1.0 out of 5.0 by went through 4 of these- well actually i went through 3 of em and decided when i returned the 3rd one and they replaced it- i have decided to sell it NIB. i thought the first one was a lemon, when the second one went - i thought well maybe the pressure is excessive so i recalibrated my compressor to 75psi under the 80 max noted in the materials- when the 3rd one went- i realized it must be a design issue which bummed me out because for some reason i really wanted this guy to be a great long term tool for me. FYI the entire time this was going on, my Porter Cable which was a less expensive unit, never once had an issue- March 25, 2014
Rated 5.0 out of 5.0 by Easy to use and just works great Purchased for a crown molding project I was working on and some finishing work and it does the job with ease and was a pleasure to work with September 9, 2013
