Deep-Fascia Percussion Technology
Frequently Asked Questions
Does this actually do anything, or is it another gadget?
Does this actually do anything, or is it another gadget?
It does one thing well: deep percussive massage on fascia and lymphatic pathways. That's an established manual-therapy technique — the ring just lets you do it yourself, daily, without booking a session. What it won't do is work if you use it twice and stop. The routine is 20 minutes a day for 30 days.
Will it make me lose weight?
Will it make me lose weight?
Yes. What it does is release trapped fluid and tight fascia, which is what makes a lower belly look puffy and rounded even when the scale hasn't moved. Most women notice a flatter, smoother look long before the number changes.
How soon will I see something?
How soon will I see something?
The de-bloating effect is immediate: most women see a visible difference after a single 20–30 minute session. The lasting change in how your waistline looks builds over three to four weeks of daily use.
Does it hurt?
Does it hurt?
No. It should feel like firm, deep pressure — intense on the higher levels, never painful. Start at level 1 or 2, stay there for the first week, and move up as your tissue adapts. If it stings or you brace against it, you're a level too high.
Do I have to hold it the whole time?
Do I have to hold it the whole time?
Only if you want to. On your waist, the belt does the work and your hands stay free. For thighs, arms, back or shoulders you hold it by the frame — it's shaped as a grip for exactly that.
Can I wear it under my clothes?
Can I wear it under my clothes?
Yes. It's 13 cm across and sits flat against the body, so it disappears under a loose top or a hoodie. It's quiet enough to use at a desk without anyone looking up.
Will the belt fit me?
Will the belt fit me?
The band is wide elastic with a hook-and-loop closure, so it adjusts continuously rather than in fixed sizes. It's built to fit generously — if it doesn't fit you, that's exactly what the 90-day guarantee is for.
How long does the battery last?
How long does the battery last?
Up to six hours of use per charge, which is roughly two weeks of daily 20-minute sessions. It charges over USB-C with any cable you already own.
What if it doesn't work for me?
What if it doesn't work for me?
Ninety days, money back. Use it properly for a month — if your waistline looks no different and you're not sold, send it back and we refund you. You don't need to justify anything.
