Long time fan of Makita cordless tools. See market reviews. Suitable for finishing work. But if you need to process a large area or grind off part of the material, then you need to choose either a grinder with a Velcro nozzle or a belt grinder. For finishing work or when it is inconvenient to climb with wires, the car is good. Choose the right consumables. The dustbin is well thought out. I am satisfied with the purchase. A good option. Yes, there are tons of videos on YouTube, including disassembling the screw and assembling the machine. Repairable. Parts are not a problem. Do not sand the plaster! Not intended. I will add a photo later.
