M4 4-Volt Lithium-Ion 1/4 in. Cordless Hex Screwdriver (Tool-Only) is rated 3.5 out of 5 by 10.
Rated 3 out of 5 by from I bought the $66 drill because i repair electronics and needed a tool to remove the insane amount... I bought the $66 drill because i repair electronics and needed a tool to remove the insane amount of small screws from laptops and flat screens. The price is very steep for just the drill, compared to the dewalt cordless screwdriver/w gyro tech (it is $69.00, it comes with a battery and a charger). I never used milwaukee, so i gave it a shot. I hooked it up to my bench power supply and first noticed that it does not have a motor shaft brake like the dewalt. When you let go of the drive switch it continues to spin for a 1/4 turn, which is not good on the soft screws in electronics. The torque adjustments are too strong, even at level 2, the lowest. I am right handed and i noticed that the drive/reverse buttons are placed for right handers only, not good for lefties. The speed level switch is tough to adjust. Accessories for this drill are not sold at any of my local home depots and i have given up on this thing. I have owned it for a little over a week now and decided to give it to my brother for christmas. I bought the dewalt. Now it is his problem to find a battery with a charger, under $60, lol. There is nothing i liked about this model and i regret buying it.

I had this tool for a little over 3 years. I used it daily from putting in devices to mounting boxes on metal studs or on wood studs when my impact wasn't close enough. It was dropped several times, rained on several times and pretty much abused. While the torque isn't fantastic, that's what they make 18v things for, it was the one tool I always depended on. The only problem is someone wanted it worse and now I'm going to have to get another. As far as having more money invested in my 18v tools than I want to add up, I will invest the small amount for this little M4. You can have the M12's, they are cute but don't have the power I want and get from the 18's. Life is just much simpler with this little tool.

Rated 1 out of 5 by from M4? Really? If you want to sell these make it M12 Firstly, I asked Milwaukee for this years ago. It responded with...we don't discuss new offerings. Fine. So I waited more. Then, ALAS! it's here! Ah...M-what? Four???! I can't believe it. Well, Mil, seriously I doubt these are flying off the shelves and it's because NO ONE wants a sole M4 platform battery and charger for one tool--especially when some of us are $100,000+ deep in M12 and M18. Please, for 2016, re-introduce this in M12. I promise I will be the first to buy it...and as a bonus, get it done by June and I'll even buy the kit: batteries and charger even though I probably own 50+ charges and 100+ batteries. Best wishes in 2016 and Happy New Year! Thanks for everything else M12/M18 this year. Great stuff!!

Rated 2 out of 5 by from Disappointed Used once to twice a day to change tooling--about 40 set screws. Works very well in terms of holding a charge, feels solid. However, it was dropped (on a concrete floor) the second day and the switch was damaged (repaired on warranty, though). A few months later, the highest torque setting produces less than 4 in. lb. Will be sending it in again.
