I got these to run through my Hitachi NR90AE and they work well enough. I ran into feed problems every so often and I probably would not have noticed it if I had not also had to go buy more of these, but a different brand, from my local hardware store. They were GripRite and once I started to run those, I did not have a single misfire and all of the grip rite nails drove in to the proper depth. It was like they were lubricated and the B&C were not, though neither actually is. Anyhow, I could have easily gone through the entire project and been happy with these nails if it was the only ones I had. Price wise, I think the big box store was as good on price if not better and came in a larger quantity. So I probably would not buy these again if/when I have to. My recommendation would be to shop around.
