★☆☆☆☆
Not Effective
I bought this product in December 2019, when I used it for few times it burned my forehead badly and left me with a permanent scare, it’s so bad. Also, it did not boost my performance in anyway. I think it is a placebo effect for people who gave it 5 stars. I don’t like to be negative, but save you money for a different device.
