Designed to maximise power and comfort, the rotational control design ensures that the blower does not twist in the user's hand in use, reducing hand and wrist fatigue. Air intake is designed with side, and front facing vents to prevent the blower from sticking to the operator's leg under right handed operation. Straight blower pipes can cause the blower to twist under operation. ECHO's rotational control system ensures the blower is balanced in the operator's hand, reducing strain on the operator's wrist.
