How strongly 4 sources agree — expert labs and real owners, with community voices weighted heavier. Not one reviewer’s opinion; the pattern across all of them.
- Brushless motor delivers more power and longer runtime than brushed alternatives
- Paddle switch design improves safety — grinder stops if dropped
- Compatible with entire M18 battery ecosystem (drills, saws, vacuums)
- Cordless means battery dependency — heavy grinding drains batteries fast
- Kit price (~$199-$389) is higher than budget corded options
- Heavier than corded grinders of similar disc size
