Manual takes some repeated reading to get the steps but never had to go back after the first actual run. I now use it for every important drill. So easy to get a fresh sharp drill bit.

Bought one few months ago. Takes a little while to get the hang of it but them youve learned how to use it properly and can sharpen those broken or dull bits efficiently and accurately. If the tip of a bit is broken, simply sharpen it first roughly on a bench grinder then finish it up with the Drill Doctor.
