Yes they are very pricey especially the latest model ENS from Dr. A. A. Karasev.
About ENS
This device simultaneously supports all 3 patented technologies of treatment developed in “LET Medical”: SCENAR-therapy, COSMODIC-therapy, ENS-therapy. This is likened to that of an electronic bio-feedback, which returns data to the brain in order that it can enable the body to correct cell function. It is used for recovery and rehabilitation of the body and is not primarily concerned with fixing conditions but more with finding causes and impairments and correcting them.
Is it worth it?
You bet it is, if one can afford… think of it like the Star Trek healing devices, it just works. Pretty much covers everything and the main thing that it does is not to treat the symptoms but to fix the cause, great for Acute pain problems etc … but it shines in Chronic illness, I had many success with it from treating people with chronic arthritis to simple types of pains that would take weeks or even months but with this device it gets done in no time, it turns the impossible to possible.
By the way the device in a nut shell only reads and sends the right impulse signals using your nervous system, the body interprets this new information and starts the healing process, at the end of the day it’s the body doing the healing, the device is just the carrier sort to speak but behind of this simple process, the how it does it … one word - beyond Genius, no wonder it’s impossible to even copy it, the tech is more than 20 years advanced than today’s technology.
And no, it’s such a fragile device inside because the way it works, opening would just break the circuits has most of it is very loose since the parts needs to vibrate at certain frequencies and oscillations, even shaking the device is a big No
You might call me crazy but somehow the more you use it, the more it becomes part of you has a healing device, it’s like some sort of a living AI, it knows want to do, and your intuition grows with it. I got it before even knowing Sapien and using both of them it just adds another level
Here’s some publication verified cases by professionals
