This practice weapon is very light and durable. I purposely hit myself on my head, arms, legs, and stomach and barely felt anything. Now of course it may hurt when you get hit with full force and speed, but obviously not as much as a metal or wooden nunchaku. Why only 3 stars? Well, it could have been a bit heavier. That's just my personal preference though. It also could have been a little safer, but it was still pretty safe. I recommend this to those who have never used the nunchaku before and wish to become better at the techniques. Unless you don't mind some bruises, this is not to be used to full contact spar with anyone.
