The gloves are a pair, and each one needs its own device, which is why this pack has two M devices rather than one. Together they treat both hands and wrists at the same time.

The M runs on microcurrent - imperceptible, no muscle contraction, up to 10 hours at a time - so the gloves can be worn while you get on with things rather than sitting still for a session. The Perfect Conductor spray helps if the sensation feels uneven, particularly on dry skin.

Everything included is matched to the devices, and comes in for less than buying each piece separately.
