Not an Activator [SEP] Because Activator's are so expensive now, I decided to try one of these in place of a new Activator.  I have noticed that it is much lighter than my Activator and also does not have as much power.  It seems like the spring in the CAT is lighter and does not deliver the same power as my old Activator.  Time will tell if I really like it...  I do like that it is lighter.  I am a Chiropractor.
