Question 1

Is this truly "professional-grade," and how do the two frequencies work?**

Accepted Answer

While it delivers effective therapeutic ultrasound for home use, it's designed to be portable and safe for self-treatment. The dual frequency is a key feature: use the **1MHz setting for deeper tissue** (like hip or deep shoulder pain) as it penetrates further, and the **3MHz setting for more superficial muscles** (like calf or forearm strains). Many users in reviews love having both options for tailored relief.

Question 2

What's the real battery life, and what gel do I need?**

Accepted Answer

Battery life varies with frequency and use. On the lower (1MHz) setting, you can expect longer sessions, while the high (3MHz) setting consumes more power. For context, some YouTube reviewers noted getting 4-5 hours of intermittent use on the high setting. **A water-based ultrasound gel is required** for safe operation. A small tube is often included to start, but for regular use, purchasing a larger, affordable bottle is recommended—a common tip from experienced users on social media.

Question 3

How durable is it, and what if I have an issue?**

Accepted Answer

The device is built for regular personal use. To ensure longevity, avoid getting gel in the charging port and store it in the included case. It comes with a standard manufacturer's warranty. Most concerns we see are isolated, but if you experience any issues, our customer support team is here to help with troubleshooting or warranty service.

Question 4

Who is this massager best suited for, and is it safe for sensitive areas?**

Accepted Answer

It's ideal for active individuals, those with recurring muscle stiffness, or anyone seeking targeted pain relief at home. It's generally safe for areas like knees, shoulders, and the lower back. **However, we always recommend consulting with your doctor or physiotherapist first**, especially for use on the spine, neck, or if you have specific health conditions. Many satisfied customers are folks who've cleared it with their healthcare provider for a home care routine.

Question 5

Can I use it while it's charging, and what's the return policy?**

Accepted Answer

For safety and battery health, we advise against using the device while it's plugged in. Please use it cordlessly and recharge as needed. If you're unsure, our return policy allows you to try it risk-free. Please check the product page for the specific duration and terms of the money-back guarantee, so you can purchase with confidence.
