My almost 5 year old Jujitsu student grandson received the training dummy on recommendation of my son, who also trains in a Jujitsu with his son, and helps teach (he's a 2nd Dan Black Belt in Tae Kwon Do, and trains in mixed martial arts). My grandson jumped on it, hugged it and said it is "the best!" I was impressed to see my son immediately demonstrate 15 drills with the dummy for his son. He felt it was great quality, sturdy, and especially liked the straps in the back for holding it during drills. We are a martial arts family. This grandma has earned 4 degrees of black belt, 3 in Tae Kwon Do, by age 40 and another in Tang Soo Do at age 61. I have been pleased with the prices and variety of martial arts supplies at Amazon. IMPORTANT NOTE: This training tool, along with other martial arts equipment should be used primarily by students getting professional instruction and under supervision of adults.
