I have one. There is more to it than two pieces of wood/boards. There is a thick pad behind the leather padded boards. The foam pad gives it resistance and bounce. It was effective. It does not offer as much resistance or bounce as the traditional makiwara. The strength of the resistance has dierct relationship to the strength of the punch. I have stopped using it after I purchase a makiwara base that is mounted/bolted on a platform. It looks like a traditional makiwara except it is bolted to the wooden platform, and your weight keeps the platform from moving.
