I have been training with REACT Defense Systems for over 8 years and I have to say, the review thus far has seriously misconstrued anyone who views this page. Contrary to the opinion about their contracts, they offer a standard training contract, I should know, I AM a lawyer. It seems other reviewers made a commitment that they could not keep and chose to use Kudzu to voice their frustration at themselves for doing so.
Krav Maga of Chandler, and all their facilities for that matter, offers the most realistic modern day self defense training there is in AZ. All of their instructors go through thousands of hours of certification, and on-going training, to be able to teach Krav Maga as well as their various other programs. As for the training, it is the most intense workout and self defense that I have ever done. Anyone who says otherwise has simply not trained here. So don't let the reviews out there misguide you, this place is the only destination if your looking for real self defense and not just another karate or MMA gym.
