It is very effective when used. I have only used it three times. I have purchased another massage machine, so I no longer use this one. Since it is a Chinese product, it needs to be used with a transformer in Japan. I also sell transformers, and you can get a discount if you purchase them together. *If you purchase, please agree to Eco-Mercari delivery.
