Query: Win some you lose some!

Arrived quickly, but I paid extra for that. Did not work at all out of the box! VERY annoying. A weekend set-aside to roof with a friend. Went to the orange Bigbox competitor and paid a LOT more for a new one. But it worked well. Fires two nails off from time to time, but otherwise great. So for the NEW product 4 stars. For the recon version from Amazon - ZERO! And took me four weeks to get my money back.
