I've been using my Norelco vacuum trimmer since 1995, or maybe 1996.
Sure the NiCad battery no longer holds a charge. Whatever, I just use it plugged into the wall.
And yes, it does take a second to initialize.
But I refuse to replace it until there's an upgrade with silver oxide power cells.
Build liek a tank, she is. And served me well, she has.
That's a testament to the power of meticulous maintenance, and the quality of Philips' electronic gadgets!
