The Volas Vitality™ MagicPro 2.0 is a wearable neck device. The clearest non-medical line on the page is everyday home comfort.
Use it at home as a compact wearable. Do not use the discomfort or recovery bullets as proven clinical results. If you have a neck injury, ask a clinician.
There is one default variant. Battery, charger and mode specs are not published.
See the Volas Vitality MagicPro 2.0 if that home-comfort setup is what you want.
