【Durable & Sturdy】: The thickened and widened stainless steel scraper ruler, the aluminum alloy motor's shell, and the thickened aluminum machine's head, combined with spray paint, offer wear prevention and long-term service life. 【Stable Running】: The two extra stainless steel reinforcing rods are fixed on the scraper ruler separately, which form a stabilizing triangle structure that can provide a more stable operation experience. 【High Working Efficiency】: The brushed all-copper motor has a power of 48W, a rotating speed of 3000-6000r/min, and a vibration frequency of 23000Hz/min. Also, the equipped 7500mA battery is fully charged and can be used for about 2-3 hours continuously, making your leveling work be finished quickly and easily. 【Safe to Use】: The overheating protection can ensure the safety of personnel and equipment during use and reduce the risk of accidents. 【Protective Packaging】: The machine's parts come in a foam that resists common compression and falls to prevent product damage in transit.
