One thing that makes Flex Mini different from other similar products is the unique construction. It has 3 pre-positioned and medical grade gel pads that would make your buttocks and upper back of your thighs are fully covered. Once you turn on the power and start the toning session, the signals from the pads would reach out and focus on your nerves which could stimulate the muscles effectively.
Even if you wear it while you are doing your work, the effectiveness would not be reduced as long as you wear it everyday for at least 30 minutes. It is because the Electronic Muscle Stimulation technology in Flex Mini is pretty advanced and claimed to be useful.
