It is not of good quality, and even if it doesn't have a single wire at the edge, it renders it useless because it scrapes your head. Try another company.

I used it for one day, the plastic parts on the edge of the iron came off on one of the rods and now it's useless. The top part had a metal ball that came off on its own...

For me, who does professional massage, this specific product is a very useful tool for my work. I recommend it to everyone..!!

When my wife bought it for fun, I laughed. I thought, "What kind of massage can it do on the head?" Three months later, I can't let go of it. It really relaxes the head.

Very good, you relax immediately, it calms you down, and above all, it is cheap! You just need to find someone to shake it on your head!
