This is my 2nd Makita tool in their current lineup. My older hands have problems with gripping and turning and the smaller 1/4 and 3/8" socket wrench drives can be difficult for me. So this power version is a real improvement for me! The grip is big and comfortable and the switch is easy to operate. It's only downfall is its size, but of course you can use socket extensions etc..
The drive itself is really torque-y, very strong. I don't have a way to measure it, but it's perfectly in range for a 3/8" drive. It's mostly helpful for just spinning down the nuts and bolts without causing the strain to my hands, but is also just plain helpful for repetitive tightening.
The bag is meh. I mean, it's a plain square bag that is almost an afterthought - it doesn't really fit right but it will hold the tool, drive inserts, batteries and charger (all in a jumble).
Overall, a very nice tool with a very ingenious drive mechanism. I can almost hold it back with my hand, but put it on something that is hard to turn and the drive really works at it. For most household and hobby tasks, it will be great. Of course, the batteries are compatible with many Makita product sharing the battery/charger platform so you can build a family of tools for your home or shop. I like this one a lot.
