Z-Ultimate Castle Rock, but under a different name on Unilocal?We were new to CO last year and tried the free trial lesson for our son. We decided to give it a try and paid the(reduced) $ 250 startup fee and $ 200 a month. As we progressed we found out that there are many more fees and charges associated… testing fees, almost $ 300 for sparring gear(they discourage you from buying it anywhere else, but I got it for $ 20 at a garage sale), tournament fees & more! After 6 months we decided to remove our son. They tried to charge us almost $ 800 to remove him! After calling their offices in CA we were able to get it reduced to just over $ 500. Long story short, look for a month to month place that will not charge you to leave. Our son is now in karate at our gym(LifeTime Fitness, Parker) for $ 40 a month, no other associated fees or extra gear and we can leave whenever. Funny thing is my whole family of 4 joined this gym(with karate and swimming lessons) after leaving Z Ultimate and we are now paying less for unlimited access at this amazing gym than we were for his Z Ultimate classes.
