The flexi-arm is part of the most recent innovation line of the LG Sonic. This product has been  especially designed to make the installation of the units  easier. Besides that, they offer the possibility to aim the LG Sonic unit even better, leading to a better result of your ultrasound treatment. The connecting arm is flexible and it can be adjusted to fit every (possible) application,  where previously improvised techniques, such as ropes and poles were used.
