The appearance of this kind of sleeping instrument is ok (a bit like a hair band tied to the forehead), and there are two modes: relaxation and sleep. After use, there is a slight tingling sensation similar to acupuncture (the intensity can be adjusted by itself). After use, I feel that this is a traditional electric moxibustion instrument, which seems to have some effect on relieving headaches.
But after using it for three days, I didn't feel the effect of helping sleep, and I couldn't set the use time and turn it off automatically because it was more troublesome to wear it on my head.
To tell the truth, the instant brainwave sleep instrument is a bit expensive, but it is found to be expensive after use, and the products have given Bian Xiao several grades in all aspects.
The appearance of the product is full of science and technology, which is the same as that of high-end mobile phones, and slightly smaller than mobile phones, so it is very convenient to carry.
In operation and use, the sleeping instrument has two buttons, and the power button is often pressed to turn it on. The other is gear adjustment. A * * * has six gears, the operation is super simple, and it is not difficult for the elderly to use it.
