i work with birch and oak.i bought a few of these to compare against the paslode nails. after shooting 10 nails, 1 bent out of the wood, ruining that project. if you bend them, you will see that they are made from softer metal than the higher quality paslode nails.If you are working in the garage on rough carpentry projects, i think that they may be ok. But dont use them for high quality, visiible projects.these are soft like the new porter cable nails. seems like after production was moved to china, they are using cheaper steel.;-((
