Your shoulders charted all night. Your lower back ran the codes with you. This is the twenty-minute session they earned.

The dual-channel TENS/EMS stimulator sends gentle electrical pulses to tired, overworked muscles through adhesive pads. Two channels means two areas at once — shoulders and calves, lower back and feet — each with its own intensity control.

Six modes. Nineteen intensity levels. A rechargeable battery that runs up to 40 hours, and reusable, washable hydrogel pads. The palm-size controller works one-handed, timer included.

Best for: the full-body wind-down on your day off. Set the timer, pick a mode, and let it do the work while you do absolutely nothing.
