CORE is designed to be reusable and can be recharged and used continuously.
- When a chest-strap, heart rate monitor strap or arm strap is used, the CORE unit can be left on the strap (and only removed if the straps are washed).
- The medical-grade skin-adhesive patches are single-use items and specified for use for one day (they actually last a bit longer though are not recommended for showering, swimming or active sports).
- If the device is swapped between people, the medical grade plastic is designed to be non-irritating and can be simply cleaned with alcohol for hygiene.
