Excelente Herramienta para tareas delicadas y no tan delicadas
Me gusta por qué hace menos ruido que una llave de impacto tradicional. Es compacta y de excelente manufactura. Tiene 4 modos. En el modo 1 se puede usar para cosas delicadas y minimizar el daño a las puntas que no están diseñadas para impacto y tornillos mas delicados y esta es la principal razón por la que compré la herramienta. No la uso para tareas pesada por lo cual no puedo opinar con respecto a eso.

Both satisfying and efficient
This is my first Milwaukee tool, and one of the first power tools i’ve bought new. Coming from eBay 12v lithium Makita brushed drills/drivers, of course the jump from brushed to brushless is impressive. Despite loving the fine, instant and precise trigger actuation of my Makita tools, this definitely competes and maybe isn’t exactly as slick, but in use I’ve never noticed a difference. In terms of everyday usability, it’s surprisingly heavier which is the sole reason I went 12v for both lineups but in use I absolutely don’t mind the extra weight. It’s never felt cumbersome or uncomfortable. Now for the elephant in the room, the hydraulic impact mechanism. Not only is it substantially quieter which I love and is honestly the main reason I bought it, but the impacts are both more precise and repeatable between screws. It feels like my old Makita just “goes ham” and makes a racket, this M12 Surge quietly cranks out precise repeatable and powerful blows. It feels more smooth premium and controlled. My favorite features are, in order: the quietness of impacts, selectable speed, one handed bit chuck, and precision/premium feel of using it day to day. I’m really happy Milwaukee is still giving their m12 line some love as not everyone needs the power and increased weight and bulk of 18/20v lineups. Overall this is my new go to for driving screws and such into anything as it’s honestly just satisfying and easy to use. The price is actually pretty fair considering I’m usually a value shopper and don’t buy new. I’m impressed and hope to get a long life out of it. I feel and see no reason why it wouldn’t last, and if it somehow doesn’t I like this enough I’d consider purchasing another if that day comes.

Another great Milwaukee tool!
Great milwaukee tool as usual for milwaukee. Not as much torque as the solid mechanical internal anvil based driver but smoother and much quieter. Small and compact for comfort. It definitely has its place. Battery life is pretty much the same. I can see tool longevity being something to note given the smoother delivery of torque but time is the ultimate test. That being said I use mine every day for work and alot!

Excellent value.
A quality product. Does the job well. I have about 15 cordless hand tools. This is one of the most-used. I left one of these out in the open with a few other tools when a washing machine delivery crew was in the house. They must have liked it too, because I never saw it again.

Just Buy It!
I have a Milwaukee 1/2" drill & driver set. The do very little since buying this. I love it. Its powerful, quiet, compact and light. I kept telling myself that my current set was sufficient, but the Surge is my go-to now and the others are my backups.
