I bought this a priority sander sanding drywall. I know that it is actually a random orbit sander is the right, but since I work too much wood I have gained this sander. Really surprised me positively grip the low vibration. This makes longer work very pleasant. The suction bag, or what should always be the one I have not yet used this and can not judge thus. I always use the grinder with an industrial vacuum cleaner and that works very well. Mi the right sandpaper, I use only Hitachi, Makita BO3711 funktionier the very good.
