Melissa knows about this.
I had to temporarily suspend the hair removal campaign, secondarily to "circumstances" and other varied forms of GID and transitional 'fun', but I will be resuming in a week, or so.
Mine was not modified to produce higher output, but to reconfigure the circuitry and supplant the 9 VDC battery power source with a 9 VDC output wallpack.
I've cleared quite a bit and speed and proficiency is very satisfactory, at this point.
