            This grinder is a beast. I have used many different brands in the past and my visual inspection of it seems to be well built. I believe Makita can improve the handle with the finger switch better for those who have smaller hands and wearing gloves don't help activate the switch. I wish Makita would make a center handle for it but not for this model that I could find.
