FAQs on Devices & Choosing

coMra devices are built for years of daily service – many customers are still using theirs after more than a decade. Every device carries an 18-month warranty covering defects in design, materials and workmanship; registering within 90 days of purchase activates full coverage. After the warranty period, servicing remains available through a global network of service centres at a minimal charge.

Yes – coMra devices use low-level lasers (Class IIa infrared in the Palm 2 and Pro, Class I green in the Palm Green) designed for home use by people of all ages, with no overdose risk. Two firm rules apply: never point the laser at open eyes (the infrared beam is invisible; close the eyelids when treating around the eyes – the same rule applies to the Palm Green's visible green beam), and keep the device at least 30 cm away from cardiac pacemakers or neurostimulators. If you are sensitive to the laser, the Palm 2, Palm Green and Pro all let you switch to a reduced power setting via the Function button.

The pulse frequency selects the depth and type of tissue the treatment addresses, and every coMra device lets you set it per protocol point. In brief: 5 Hz works on internal organs and deep tissue, 50 Hz on muscles and structures near the skin surface, 1000 Hz on skin and sensitive nerves, and the Variable setting cycles through all three for joints and multi-depth needs. You never have to work it out yourself – each protocol in the user guide states the frequency for every point.

The main coMra user guide – with protocols for over 200 conditions – serves the infrared devices: Palm 2, Pro 980 and Pro 905. Every protocol uses the same simple format of numbered points, minutes per point and frequency setting, so the method carries over if you ever change devices. The Palm Green follows its own dedicated Harmony guide for stress and nervous-system work, and specialised guides (Beauty & Wellness, Body & Mind Performance, Veterinary) extend the library – all free to download.

Just the device and the free coMra user guide – nothing else. The user guide (printable PDF, mobile app for iOS/Android, or web app) gives step-by-step protocols listing exactly where to place the device, for how many minutes and at which frequency, for over 200 conditions. The device is applied directly to clean skin, with no gels, creams or consumables involved.

Every coMra device runs on a rechargeable lithium-ion battery with built-in protection circuits. The Palm series uses a 650 mAh battery giving up to 4–5 hours of continuous use, with LED indicators showing battery status; the Pro carries a much larger 3000 mAh battery for extended sessions. No mains connection is needed during treatment – the device is fully cordless in use.

The coMra Palm 2 – it is compact and lightweight, fits in a handbag or pocket, and runs for hours of continuous use on a charge – it was designed for treatment on the go. The Palm Green shares the same portable format for stress relief while travelling. The Pro is also mobile-capable: it ships with a durable leather-coated magnetic case made for moving between home and clinic.

Yes – the Pro 980, Palm 2 and Palm Green are all recommended for pets alongside the family. There is no need to shave or pluck the treatment area: fur and feathers conduct the radiances. Free veterinary user guides (Cat & Dog, and Cow & Horse) map animal anatomy and give complete protocols.

Yes. The coMra Pro 980, Palm 2 and Palm Green are each recommended for the whole family, including pets. All radiances operate at low intensities within a broad therapeutic window, so there is no overdose risk and the same device is safe for babies, adults and the elderly. One device simply travels from family member to family member, following the protocol each person needs.

Ultrasound is the fourth radiance, present only in the Pro 905 and Pro 980. Working at low frequency alongside the laser, magnetism and colour light, it accelerates the transport of fluids and molecules through tissue and helps ailing cells reorganise internally. In practice this means faster recovery where the body has serious work to do – significant injuries and degenerative changes.
