Everyone that has actually put his or her finger into table saw blade, raise the hand.
I have. I hope that give me extra insight into this. It should at least give me a real perspective. I’m 52. It happened over ten years ago. I was tired and in a hurry.
I can tell you that it will never happen again. How hard is it to simply keep your hands away from the blade. Stay away from the blade is the best "fix". The bad part is that I knew better. I work with tools for a living. If it flies, floats, has wheels or high voltage, I’ve fixed it.

I can see the advantage of this device. Especially in a production environment. That being said, I wouldn’t want it on my saw. Repeat, not on MY saw. As people may have pointed out this is going to add to the cost and the manufactures, either for liability or by government mandated will pass that on to me.
I noted that he inventor didn’t put his finger into it hard, like would happen in the real world. He just touched the blade very gently with the tip. And he wet and chilled the finger first. Tricky. However I’m sure that the device would minimize damage to the finger though. Better than nothing for sure if a person wanted one on their saw.
Who knows, it might give such a sense of security that it would cause a few blades to be trashed.
