FAQ & How to Use

FAQ & How to Use

Have questions? We`re here to help
Have questions? We`re here to help

Q1: Is it safe to use every day?

Yes. The device is designed for daily use. We recommend starting with 20 minutes per day, 3-5 times a week, to allow your body to adjust to the stimulation.

Q2: Will the EMS shocks hurt?

Not at all. It creates a strong but comfortable tingling sensation that causes your muscles to contract. It should never be painful. If it feels too strong, simply lower the intensity level.

Q3: Is it suitable for postpartum recovery?

Yes, it is designed to help with abdominal muscle separation (Diastasis Recti) and core tightening. However, we recommend consulting your doctor before use if you are less than 6 weeks postpartum or had a C-section.

Q4: How long does the battery last?

The 2500mAh battery lasts for approximately 4-5 sessions (depending on heat/light usage) on a single charge. It recharges fully in about 2 hours via USB.

Q5: How long until I see visible results?

Most users report feeling immediate muscle relief and warmth after the first session. Visible sculpting and toning typically appear after 4 weeks of consistent use (3-5 times per week).

Q6: My skin feels a bit red after use. Is that normal?

Yes, slight redness or warmth on the skin surface is a normal reaction to the increased blood circulation and heat therapy. It should subside within 30 minutes. If irritation persists, discontinue use.

Q7: How do I use the belt correctly for the best shaping results?

For best results, wear it directly against bare skin; apply gel first if your skin is dry.

Q8: How should I clean and maintain the device?

Always turn off and unplug before cleaning. Use a soft, slightly damp cloth to wipe the surface. Do not use harsh chemicals, bleach, or abrasive cleaners. Store in a cool, dry place away from direct sunlight when not in use.
