Are there any consumer grade devices that are safe/recommended?

I just bought one called Powerbreathe on eBay, they seem to have mechanical and electronic ones. Probably can’t hurt, I’ll give it a go. Drop me a line if you have questions, I should have the device in hand in a couple weeks.

Search for "power breathe" on Amazon. Found them by typing in IMST.
