AI Review Summary:

Across verified reviews, users praise the tool’s strong power for a 12V class, compact size, and excellent control from the 3-mode selector and variable trigger. Many highlight effective use with 2 in. cut-off and wire wheels and appreciate the LED and reduced hose clutter versus pneumatic models. Neutral observations note best performance with higher-capacity M12 batteries. Common complaints include runtime limits on small batteries and that heavy grinding can bog the tool compared to corded or 18V units. Representative quotes: “Plenty of power for exhaust and bracket work,” “Great control with the speed modes,” and “Works best with a 4.0Ah—1.5Ah drains fast.”
