Frequently Asked Questions

What is ULTRIIX S1?

ULTRIIX S1 is a wireless ultrasound massager that uses 1MHz therapeutic ultrasound waves to penetrate 4cm deep into muscle tissue. It soothes pain, stiffness, and fatigue — the same technology trusted by physical therapists.

How is it different from a massage gun?

Unlike massage guns that only vibrate the surface (1-2mm), ULTRIIX S1 uses ultrasound waves that penetrate 40mm deep into muscle tissue. It is whisper-quiet, lightweight (280g), and won't cause bruising.

How long does the battery last?

The built-in 2000mAh battery provides up to 120 minutes of continuous use on a full charge. Charging takes approximately 2 hours via USB-C.

Is it safe to use every day?

Yes. ULTRIIX S1 features auto shut-off timer, smart skin-contact sensor, and 8 adjustable intensity levels. It is designed for daily use. Each session is recommended to be 10-15 minutes per area.

Where can I use it?

Effective on most major muscle groups: neck, shoulders, upper back, lower back, arms, thighs, calves, knees, and ankles. Avoid use on face/head, directly over the spine, or open wounds.
