Yes, I have a ton of experience with them. I really really like them and the fact that the weight adjustments get the weight away from the riser on the bow. I currently think they are one of the nicest stabilizers out there. The owner of the company (Nunzio) is a real nice guy too and will do anything to make sure he has happy customers. I also really like some of the higher end vibracheck products as well as doinkers.
