The shoulder wrap carries large silicone conductive pads that can be isolated to the front, the back, or either side of the joint - which is why this pack includes three devices rather than one. Run all three and the whole shoulder is covered at once.

Two Lite devices handle TENS and EMS; the M runs microcurrent, which is imperceptible and can be left on for up to 10 hours. Each arrives in its own box with its own gel pads, so all three work independently of the wrap when you want them elsewhere on the body.

The Perfect Conductor spray is included - it helps the sensation spread evenly across the wrap's fabric pads.
