I have had my Harbor Freight drill for over a year. Here's how to make it go longer than expected:
#1) Take it apart. Add machine grease to the bow of the thing (where the gears are)
#2) The wires where they come through at the stern pulled out and later shorted out. Think spark then nothing. I fixed that (standard way, butt connectors, separating the wires) then put it all back together.
The machine grease is the key. Lots of lubrication out to keep it going.
Mine still works though honestly it doesn't get much use.
