After burning myself last night, I'm now qualified to pontificate upon this
matter.

I wrapped the 660 unit to my right wrist with an Ace Bandage last night and
went to sleep. After about 75 minutes I woke up with it burning and I
hastily removed it. I got up and put Emu oil on the afflicted area.

Today I can see reddened impressions of the LED's and it's a little sore but
not bad.

My idea is to use this thing in a manner like the Beck Device, since I have
a good idea that I've got calcifying nanobacteria flowing through my blood
again.

Here's what won't work:
Despite the fact that V has the lights recessed in the box, in a pressed
situation the skin comes into too tight contact with them. An Ace bandage is
the WRONG way to do this.

Here's what might work:
There is enough room along the top edges of the box to drill 1/8"
ventilation holes around the sides. I will see if I can also safely drill a
few holes in the back side. There is enough flange on the top to attach some
kind of buffer around it so it won't touch the skin, maybe self-adhering
weatherstripping pieces. I will be attaching it with only a little paper
tape next time.

When I get it worked out I'll send a photo.

More later, Daddybob
