Query: Good motor, Poor use of plastic

I bought this in 2008 and use it 1-3 times a week. The motor is still strong, but the drive shaft and gear box are made of plastic. The plastic is now stripped and can no longer turn the blade. I don't think it's ethical to manufacturer a critical moving part out of plastic that will inevitably wear out before the motor does. Last night I glued the parts together to hopefully keep this tool out of a landfill a little longer.
