not the same as a real activator [SEP] 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
