WHAT OUR CUSTOMERS SAY











The upgrade for your knee – anytime & anywhere
The new jackrelief® generation combines deep heat, laser pulses, and pinpoint vibration in a lightweight, wireless device.
Designed to relieve pain, restore mobility, and make every step easier.

Why Traditional Pain Relief Just Doesn’t Work...
Most pain relief methods like pills, ice packs, or patches only offer temporary relief — and don’t treat the actual source of your knee pain.
They can be messy, inconvenient, or even come with unwanted side effects. Worst of all, they don’t help restore mobility or joint health.
Neurovita™ is built differently:
✅ Targets pain at the source with heat, massage & compression
✅ Delivers fast relief — without drugs or messy treatments
✅ Comfortable, secure fit for daily use anytime, anywhere

Wireless & suitable for everyday use
3000 mAh high-performance battery → up to 5 hours of battery life
Only 650 g – as light as a tablet
One-hand LED touchscreen

Ergonomic design
The flexible 360° wrist strap adapts to any leg shape and holds the device securely in place – whether you're watching TV, working, or traveling.
