Question 1

Will this fit my knee if I have larger thighs or am wearing a brace underneath?**

Accepted Answer

Many users have asked this, and a few have noted the straps run snug on larger thighs (22 inches or more). The straps are adjustable, but we recommend measuring the circumference just above your knee before ordering. If you plan to wear it over a heavy brace, you may need to size up. For best results, use it directly against a thin layer of clothing.

Question 2

How long does the 5000mAh battery actually last in real use?**

Accepted Answer

Good question—battery life depends heavily on your settings. On a middle heat and light setting, most users get a full 45–60 minute session. If you run all three (max heat, max vibration, and all 5 red light levels), expect about 25–30 minutes. You'll be able to recharge it fully in about 2–3 hours.

Question 3

Is the red light therapy strong enough to feel effective, or is it just for show?**

Accepted Answer

This is something we see discussed often. The 72 red lights combine 660nm and 850nm wavelengths, which are clinically recognized for deep tissue support. Many users report reduced stiffness after consistent use, though some expected a more intense "beaming" sensation. It's a gentle, therapeutic warmth rather than a high-power laser—so it works best for regular maintenance rather than instant relief.

Question 4

Can I use this on my elbow or shoulder without it slipping off?**

Accepted Answer

Yes, the wrap design adjusts well for both elbows and shoulders, and the straps hold firmly once secured. Just be aware that the shape is naturally designed for the knee joint, so some users find it fits the elbow perfectly but requires a bit of fussing to stay put on the shoulder during movement. Many TikTok users recommend sitting still while using it on the shoulder for the best experience.

Question 5

What if the size doesn't fit—can I return it?**

Accepted Answer

Absolutely. If the sizing doesn't work for you, you can initiate a return within the seller's standard return window. To avoid hassle, just keep the packaging and try it on over a thin layer at first. It's a common concern, and the replacement or refund process is straightforward—most users report receiving a response within 48 hours.
