We got off to a shakey start but after taking the time to look at the 10 minute video included with the device it was full steam ahead. I can now say that it works great after you learn how to use it, just be sure to watch the video.

The first bit took a while to get right but subsequent bits have been quicker and the set up is also becoming more intuitive. Decent quality drill bits are expensive and being able to sharpen them over and over is a real money saver.

Once you get the hang of it, it's about as easy as operating a pencil sharpener. Now the bits I sharpen and use to drill into mild steel cut into it like butter.

All in all I think this is a great money saving machine.
