Review: Correct battery for your tools - Great delivery and battery works perfectly
Review: Top stuff! - Thrilled to bits with this driver so far! It packs a far bigger punch than my makita! Feels sturdy and well built but time will tell! The 3 speed setting is helpful depending on what task is at hand. A little heavier than my old makita but that's probably because it's better made!
