Functional, versatile, and easy-to-use, it\'s an essential tool for nail-care veterans and newcomers alike. 1. This nail drill is designed for acrylic gel nails. So if you want to remove the gel polish of natural nails but you are not a professional manicurist, please use the nail polish remover pads instead of a nail drill to avoid damage to the nail bed. 2. In order to meet the requirements of professional manicurists, this product is designed to have an adjustable rotation speed of 0-20000 rpm. Please slowly adjust it from low speed to a higher speed that you like when you are using it. Do not adjust it to the highest speed all at once to prevent the improper operation from hurting your nails. 3.A high-speed motor will inevitably generate heat, so please do not use the nail rill for too long each time. When you feel that the nail drill is overheated, please stop using it immediately and wait for the heat to dissipate before using it again.

When the nail drill is rotating, please turn off the switch before replacing the nail drill bit. 5. Please do not pull the power cord or let the device drops or by other impacts. 6. Please do not use the device when the connecting wires broke and do not touch the plug with a wet hand to prevent electric leakage and shock or fire.
