Not for me seeing as the device relies on detecting a current from the finger to the saw blade and with all the strange things electricity does that I have seen - no way!
What hope for a finger 5 years and no maintenance later ..... ?
For me just slow down, hands well away and a sharp blade, now drilling machines ... thats another story, you know the one, just drill it quick dont need to clamp... oops weres the bandage!!!
