I had a very busy month last month and I can only say that I would be more tired than I feel tonight if had done all those insertions with a foot switch. Auto-sensor mode is highly efficient. The insertion numbers are incredible and clients appreciate smooth, unlabored hair removal. One must totally concentrate when using auto-sensor mode. That’s why I rarely talk during a treatment so I can move as fast as possible as determined by the difficulty of the area. Yes, the Platinum (or Pure) are great tools for this. The Silhouet-Tone VMC (microflash) works well, too, for using an auto-sensor strategy. I can name other epilators that I am familiar with and I’m sure there are even more that I have never used.
The other side of the equation pertains to eyesight and visual aid help. Without the good vision part, it is probably safer to choose to use a foot switch.
