@blackle Careful with the magnet finger tips. It's something that's still very experimental. There's no legal painkiller or anesthesia for the actual implanting allowed. And since it's done in the finger tips it hurts immensely. The biologically inert coating around the magnets metals have a tenancy to dissolve over time. And while the magnetic sense is strong at first, it tends to fade until near nothingness after a few months after the fingertips heal.
