Short answer: how often and how long can I use it? The one figure our pages give is for the Classic 3.0: up to 45 minutes continuous, then let it cool fully. For how often, follow the manual for your model and don't exceed it.[2][9]
How often and how long can I use it?
- Session length: Classic 3.0, up to 45 minutes continuous.[2]
- Cooling: let the device cool fully before the next session.[2]
- How often: our FAQ says to follow the session length and frequency in the current manual for your model and not to exceed its instructions.[9]
- Dominator: it has a programmable timer and auto shut-off to help you keep to your chosen time.[3]
- Not sure? Ask us, and ask your doctor if you have a medical condition.
