Should be getting mine tomorrow. I can't stand the jack3ds, 1mr and so on due to the fact no matter what time and lowered dose I do it prevents me from sleeping. They give me great focus and pumps with strength increases , but ultimately I pay by the price with lack of sleep. Actually they make me feel that my body is at rest but my mind won't shutdown. I'm looking for the unstim so hopefully this product will do the trick. Keep you posted .
