This Review Title is Not the same as a real Activator and the content is: I ordered this product with the hope that it would achieve the same level of effect when using the Activator protocol for a certification in Chiropractic school. The design looked right and it is a sturdy enough piece of equipment, however there is significant difference between the effect of an Activator and a J-Tech. This product did not make any discernable difference, despite having adjustable strike distance and level of force. Save yourself the time, get the real thing if you are going to rely on making real changes for your patients..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
