I picked this palm nailer because my husbands old one died after many years of use. It came with some alternative nail nose fittings that others lacked. A real bonus was the extra O rings because it is sometimes impossible to find the correct ones for your nailer repairs later on. The unit also came with a nice leather glove and a case to store it all in. I have purchased many Bostitch in the past and have not been disappointed. Also this unit has a great guarantee.
