Proto Vibrating Peanut Massage Ball Roller Black, Rechargeable, Quiet, Full Body Deep Tissue Massage, Sore Muscles. for Sports Athletes, at-Home, Workplace

I have nerve damage in my legs that tends to make my calves and feetmuscles tighten. It makes them hard and inflexable. I run this over my leg muscles for a few minutes and it turns them to jello. It sometime hurts while I'm using it, but when I'm done it's well worth the pain.

I bought this since I was suffering from lower back pain due to high mileage in preparation for a Marathon. Regardless of the reason for the pain, I was very uncomfortable.I found that lying on it using its different speeds, helped with the decompression of the affected area, reducing the pain significantly, especially after long runs.I typically use it for 8-12 minute periods, and I'm good as new.Great product!

The Njoi Proto is amazing! I've been looking for something that helps my sore back and shoulders and this is perfect, it has been one of the only things that helped my knee pain. It's cool that you can pick any color, I chose black and it is nice and sleek.

A bit after a month's use. Shape, functionality and everything we're delightful, but nothing matters if a $90 product can't even work for 2 months

I bought the njoie proto and the electro and the porto peanut massager. I really love both of them! i’ve bought a few njoie products before and these didn’t disappoint. the quality is really amazing for the price and i love the size of both, the electro makes targeting a direct area really easy. the vibrating is a nice feature as well. the proto is great for larger areas and both are really effective! i’m glad i bought both - they’re great for different areas/ needs. the electro has helped me tremendously with calf soreness and electro with back pain. I got mine in black and it looks really sleek 10/10 overall.

The product is heavy than expected. Its too much of a hard surface. Also disappointed this type products still using old style charging port easly damaged when inserting cable.
