This item was ordered as new. The details of the Revain order explicitly show this. However, received a repaired block instead. On the other hand the recon unit will work with both 16 gauge and 17 gauge shackles according to the latest version information on the Senco website, which I was not expecting from the unit pictured and described in the item listing. As a reconnaissance unit, the SNS41 only comes as a basic tool with standard papers, definitely not in retail packaging. Refund policy. Haven't had a chance to try it yet, but I will soon. If it works like new I'll leave it. Just take a look. UPDATE: Have been using this stapler for a long time. It probably clamps once for the staples, otherwise it drives them fine. It seems that adding an extra row of staples before the end of the first row can cause problems as I've found that the back row tends to lift up a bit and needs regular pressing to align the tips of the front row .
