It's all normal. Heating and discharge current work. It's been slow but everything came and works fine. I don't know if it's gonna do any good. But it's funny. If you press to the neck, then the head from muscle cuts jerks :))) I hope when I remove the effect of Parkinson will not stay with me :))))) Definitely not useless. I only tried once. And the effect is more than after the masseur. Stagnation broke, but when turning the head I do not even know how to describe. The feeling that the neck is a swivel joint. And the ball is in lubricant but lubricant with some sand. When turning, I hear my head like friction. It felt as if there were stones in their neck and they were rubbed with small granules.
It's very nice packed and quality looks very good. I tried it. It works also good. I don't know if it helps. I will leave additional feedback in 1 week It is a strange feeling. I think it doesn't help much with the pain. But it is still an okay massager
The parcel was 2 months old. Everything came whole and working. It was packed in a normal bag with bubbles. Sensations from massage are very unusual, you can not describe words. So far, the whole family likes. The only thing in the description is written: "built-in lithium battery capacity: 1600 mAh", but on the box 450 mAh. I am happy with the purchase. Thank you)
