The kit includes multiple polishing pads for different applications, and the Velcro backing plate makes swapping pads simple and quick. This versatility extends its use beyond cars to boats, furniture, or even leather and tiles.

The brushless copper motor is designed to last longer with less noise and interference. The body is made from sturdy ABS plastic, which is standard for tools in this category.

Ergonomically, the cordless design eliminates the hassle of cords getting in the way, making it easier to move around the vehicle freely. The kit’s extra attachments, including various sponge, wool, and cloth pads plus sandpapers, add versatility for different surfaces beyond cars, like wood or metal. Users should be mindful not to overload the motor at low speeds to avoid malfunction.
