How about redesigning the power system
Great trimmer with a rather unique feel and design. I am 57, a red head gone white with lots of fine hair. The vacuum is acceptable if you empty it frequently. The adjustable length setting is a  nice feature.<br /><br />Now this thing needs to have some healthy battery power and life, come on now, pitifully weak batteries with a short charge, 14 hour charging time and won't work while plugged in the wall. You best plan ahead for a trim. Not at all convenient. I'd rather have a corded version, more flexibility.  Pssst....Norelco...think Lithium Ion or Nickel Metal Hydride for pity's sake.
