I judt got these this week and put them to use right away. I always like to read the 1 stars and most were because they only got one bit. My ad said 15 bits and showed 15 bits and I got 15 bits. I drive a lot of drywall screws in wood making sets of our theater. Use drywall because we often take sets apart and reuse material. When I received them I hand fitted one in a screw. It was a perfect fit with no wobble. In fact it held the screw tight like a magnit. They are brand new so thats a good start. I had a pice that I had about 8 screws that would not drive below the wood surface with my old bits as they reached their cam out force in this hard wood. One of these new bits drove every on below and none camed out. U will see how long they hold up and report back. For now I am very pleased.
