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!

Genuine Milwaukee
I purchased two of these and whilst I appreciate the 5.0ah is the same physical size and more powerful, as an ameature DIY'er I had no real need for the bigger battery. Longevity is very much specific to each person, me as a home DIY'er these will likely last a long time from a construction point of view, not being tossed around a building site. The longevity of the cells; negating any as yet undiscovered defects, also depends on use and environment factors. But very happy either way.

Milwaukee 18v 4aH battery
Still early days to comment on the reliability, and ability to hold its charge, but Iam sure I’ll get years of use before I need to replace it. Nice and quick order turn around, ordered on Saturday had it by Tuesday.( standard delivery)

Le batterie originale Milwaukee red lithium hanno una durata superba , anche se inutilizzate per mesi al riutilizzo sono sempre cariche e la potenza è tantissima. Si sente la differenza anche nella potenza degli utensili rispetto alle batterie cinesi , che dopo un anno non funzionano più. Ho batterie originali da cinque anni e la durata è sempre la medesima. Che dire perfette.
