I'm using my new prestige model with the slide and flash function. It's quite slow. Was using on legs and it flashes about every 4 seconds. Ugh.
Then did under arms and managed to do the same thing but it flashed every 1-2 seconds. MUCH faster and loved it. Now I can't get it to do that again. It's back to 4 seconds.
So. Having a painful live chat with Philips but want to know, what speed is yours flashing at on your slide and flash function?
