It's great to have you here!

I personally don't know much about these, but from what I've googled I gather this is something you carry around with you and there is no surgery involved, yes?
This is something we should incorporate into the 'sticky' section of the forum for people to get a visual on and information to read.

If anyone else here used one of these, I hope they respond.
Thank you, Mark.....and thank you jrca for bringing up a good question!
