This is the device that relieves pain throughout the body to promote a good night’s sleep. The pain reliever is worn around the calf and sends harmless high-frequency electrical pulses that stimulate nerves and block pain signals throughout the body. The device can relieve pain from diabetic neuropathy, sciatica, fibromyalgia, and osteoarthritis in as little as 15 minutes without the need for costly prescription drugs. A built-in accelerometer detects when you are sleeping and automatically reduces the intensity of the treatment while still reducing pain. Made from thin, flexible nylon, the comfortable wrap weighs less than three ounces, allowing it to be worn under clothing during the day and making it hardly noticeable when worn while sleeping. Integrated Bluetooth connects the device to a smartphone running a free app and allows you to track and manage treatments easily. The rechargeable battery lasts for 40 hours after a two-hour charge via the included USB and AC adapters. Comes with two replaceable electrodes that last four weeks. 17 3/4" L x 3 1/2" H x 1/2" D. (2 3/4 oz.)
