So I just received my device today.
First impression : it doesn't seems cheap made, the frame is 3D printed, it's plastic but it's seems quite robust.
First use : I used it for about 10 minutes, and it really does what it says ! My scalp was way more loose after using it, and it gives a pretty nice feeling. I had some struggle at the beginning to positionate it, but i've eventually found the right position, and the device really pushed my scalp upward. Like when i touched the top of my scalp, i could feel my skin being extra loose.
can you post pics of the device?
