The Blackline looks strong and is very popular among recreational athletes and professionals. Like all Prorelax devices, it offers powerful performance and sets new standards in design and functionality. Although the self-adhesive electrode pads are of very high quality, they must be replaced regularly for hygienic reasons. Black replacement pads for the Blackline edition match the modern look of the Blackline devices and are available in three different versions, such as banana pads (115 mm x 40 mm). Self-adhesive electrode pads ensure optimal performance of the devices. Whether for TENS or EMS therapy, the self-adhesive pads are particularly soft and skin-friendly. They conform to the shape of the body, are reusable, and therefore durable. Additionally, they impress with high conductivity for optimal results.
