How do you change the massage head?
Flowsonic Pro does not have attachments that need to be unscrewed or replaced. Instead, it comes with different rubber heads that fit directly over the metal parts of the device.
To change a rubber head, carefully pull the existing rubber head off the metal part. Then select the rubber head you want to use and slide it over the metal part until it is securely in place.
Always make sure the rubber head is securely attached before using Flowsonic Pro.
