Smaller and lighter but oh so juicy!

3 years ago
These little beauties are great for the home tools. The provide plenty of power for the little jobs and recharge really fast. I have M18 as well but the reduced size and weight of M12 is really nice for small tasks.

Yes, I recommend this product.

Red and green flashing problems that people are complaining about, you have the plug the power source in first and then the battery. I ran into the same problem until I read the instruction memo from Milwaukee.

Not a good choice for heated clothing

a year ago
This probably works fine for other applications but it was received as a “free” battery with a vested jacket. For that application a 2.0 just doesn’t cut it. Very short lifespan between uses.

I have only had this item for about 2 weeks and haven’t really had a chance to fully observe all of it’s capabilities. So far though it seems like you would expect a Milwaukee tool to preform.
