OlyLife Shaken Massager (SK-M3): Technical Specifications, Certifications and Safety

This page gathers the technical details, certifications and safety information for the OlyLife Shaken Massager, model SK-M3, in one place. It goes with our Shaken Massager product page.

Unless we say otherwise, every figure and safety rule here comes from the official Shaken Massager user manual. The manual describes it as a product for health and relaxation. It isn’t a medical device and isn’t a substitute for medical treatment.

What it is

The Shaken Massager is a cordless, rechargeable massager that you wear around the torso. Two cupped massage heads, joined by a hinge, sit against your skin. A wide, soft strap with velcrose ends holds them in place, front or back.

You control it with the two buttons on the unit, or with the OLY-Watch, a wrist controller that comes in the box and connects by Bluetooth.

What’s in the box

• Shaken Massager main unit with strap assembly
• USB Type-C charging cable
• Extension strap A (short, about 300 mm, 11 inches)
• Extension strap B (long, about 700 mm, 27 inches) Note that these extensions add on to the width of the device.
• Two sleeves to hold the straps in place.

The OLY-Watch wrist controller is also included. The two sleeves slip over the strap wings on either side of the unit. The wings can’t be removed, so the sleeves also make them easy to keep clean.

Specifications

The three modes

In use, the massage movement feels like the two cups circling in opposite directions. The PEMF comes through as a gentle ripple, similar to the feeling under your feet on the Tera-P90.

How AI mode works. According to OlyLife’s product training material, the watch collects your heart rate, blood oxygen and sleep quality. In AI mode, it uses those readings to adjust how strongly, and for how long, the ultrasound, vibration, heat and RF run within a 20-minute session. AI mode only works while the watch is worn on your wrist. For sleep data, that means wearing it overnight. OlyLife hasn’t published details of how the AI chooses the settings.

The three intensity levels

Our articles explain the main technologies and what the research says: PEMF, radiofrequency, vibration and light therapy.

Using the Shaken Massager

Choosing your strap

For waists between 80 and 125 cm, the manual suggests strap B on its own, because threading both straps through the buckle can be fiddly. You can still combine them if you’d like a looser fit.

Putting it on

1. Remove clothing from the area. The unit must sit directly against your skin.
2. Position the unit over the area you want to work on, across your back or your front.
3. Wrap the extension strap around your body.
4. Thread it through the buckle, or attach it straight to the hook-and-loop fastener, and adjust it to fit.
5. Check that it’s secure before you start.

If a strap isn’t comfortable, you can lie down and rest the unit on your body instead, with the strap ends weighted down on either side.

Running a session

1. Hold the Power button for 2 seconds to turn the unit on.
2. Press the M button to move between Body Sculpting, Massage and Heat Therapy.
3. Press the Power button briefly to change the intensity level.
4. Hold the Power button for 2 seconds to turn it off.

Using the OLY-Watch

1. Turn on the main unit first. Then hold the watch’s power button to turn it on and pick your language.
2. The watch searches by Bluetooth. Choose “Shaken Massager” to connect.
3. Swipe up or down to browse the modes, and tap to choose one.
4. On the mode page, tap to change the intensity. After 5 seconds with no action, the screen returns to the mode page.

The watch also shows pop-up alerts when the massager’s battery drops to 20%, 10% and 0%.

Certifications and registrations

• CE verification of conformity under the Radio Equipment Directive (RED), issued through Intertek
• US FDA registration. The Shaken Massager is FDA registered, not FDA approved. Registration lists a device with the FDA. It isn’t an approval of any health claim. Our article on FDA registered vs. FDA approved explains the difference.

Safety and precautions

The rules below come from the Shaken Massager manual. Please read them before your first session.

Who shouldn’t use it

Don’t use the Shaken Massager if a doctor has told you to avoid physical activity or stretching. The manual says conditions such as thrombosis, severe aneurysm, acute varicose veins, skin inflammation or infection may get worse with use. It also rules out:

• people with a pacemaker, artificial heart or other implanted medical device
• people with swelling, inflammation or bruising on the head, or who have had brain surgery
• people with heart disease, severe thrombosis or a cerebral haemorrhage, unless a doctor advises otherwise
• people who have had a stroke, have high or low blood pressure, are under medical treatment or are in poor physical condition
• people with bleeding tendencies or blood disorders, osteoporosis, soft tissue conditions, malignant tumours or acute illnesses
• women who are pregnant or have recently given birth, and women during what the manual calls “special physiological periods”
• children, and anyone who can’t look after themselves
• people with limited mobility or with physical, sensory or intellectual impairments, unless supervised
• anyone with a body temperature above 37°C
• anyone with inflammation, open wounds or burns on the skin

People who are very sensitive to heat shouldn’t use the heat function.

Check with your doctor first if you have

• severe nerve damage from diabetes
• skin injuries or wounds
• frequent numbness in your hands or feet
• breathing difficulties
• an acute internal condition, such as gastritis, hepatitis or gastroenteritis
• a vascular disorder
• medical rehabilitation devices in use

If your heat sensitivity is reduced, the manual says to use it only under a doctor’s supervision, because the surface can get warm.

Times to skip a session

• when you feel physically exhausted
• within 40 minutes before or after eating
• after drinking alcohol, or when you feel unwell

While you use it

• Set the heat to a comfortable level to avoid burns.
• Don’t use it for more than 30 minutes at a time. Long use can cause low-temperature burns.
• Stop straight away if you feel back pain, dizziness, nausea, palpitations or any other discomfort.
• Don’t use it on swollen, bruised or inflamed skin.
• It’s designed for one person’s use only.
• Don’t leave it running unattended while it’s plugged in.
• Don’t use it if it’s damaged, has a cracked casing, or has been wet.
• Keep the cord and plug dry and away from heat. Don’t handle them, or the buttons, with wet hands.
• Don’t take it apart or try to repair it yourself.
• Let it rest for 30 minutes after each use to extend its life.

Charging, care and storage

• Charge it fully before first use, and promptly after each use. Unplug the charger when it’s done.
• If you won’t use it for a while, turn it off and charge it once every three months.
• Store it somewhere cool and well ventilated, away from moisture, heat, direct sun and children.
• Hand-wash the fabric cover in water below 30°C with a mild detergent. Avoid bleach. If you machine-wash it, use a laundry bag.
• Wipe the straps with a soft cloth and a neutral cleaner. Never soak or rinse them in water.
• Don’t clean it with petrol, thinners or similar solvents.

Troubleshooting

To restore factory settings, hold the Power button for about 10 seconds while the unit is charging. Press either button within 5 seconds to cancel.

Warranty and recycling

The Shaken Massager comes with OlyLife’s 24-month warranty from the date of purchase. Keep your warranty card and purchase invoice, as you’ll need both for a free repair. Lost warranty cards can’t be reissued. Damage from misuse, unauthorised repairs or natural disasters isn’t covered, though paid repairs may be available. See our FAQ for how returns and repairs work.

At the end of its life, don’t put it in household waste. The lithium-ion battery must be removed and the device taken to a recycling facility.
