Received the machine then realize it uses batteries only. Also need to use with water wetting the foot. It is dangerous for my 90-year-old mom to use water on the foot to work on the machine, easy for her to fall if she suddenly stands up or walks with a pair of wet feet. The batteries and wet foot are never mentioned in the advertising, it gives viewers a misleading image that this machine is simple and easy to use. Those hidden trouble issues are never mentioned. Also, customers are required to pay for the returning postage. Unreliable company! Terribly upset.
Pros and Cons:
Bottom Line: No, I would not recommend this to a friend
