Bought this nailer 2 weeks ago and was very disappointed that it doesn't drive nails consistently, tried 3 different batteries off (all fully charged) and the depth set all the way and it didn't drive 2" nails all the way into the jaws, I had 1" to 1 1/4" gap on each nail. Checked the depth setting and made sure she went on the low setting and it worked metabo called hpt and they said to send it back to revain i returned it for a full refund (thanks revain!) and bought a makita 15 gauge nail gun that was 2 -inch nails driven all the way into solid red oak I use good quality nails (SENCO) so I don't know what the problem is.
