Used these to build my porch. I still have a ton left over! I used these to fasten my deck board onto the joist. These came with drill bits which didn't wear out. I love the case it comes into for storage.
I would recommend that when installing boards that the center of the "tree" points down as it can flex up during season changes at the end of the boards. This can cause the screw the shear off.
I have driven a box of 75 so far, attaching 2x4 purlins to 2x8 rafters on a pergola. The include driver bit works well, no cam out so far. You do have to be sure to hold the drill straight or you might get some slippage, but the bit is still going strong. I have a box of 350 left to use and I'm pretty sure the two bits will hold out. If they do not then I have several square drive/Robertson bits that will work also.
