I use them professionally, we install gutters. I also bought them for my colleagues, they are great for driving small screws, they are small and light. I've dropped mine onto concrete from 15 feet with no problems except the end of the battery clip broke. But it still worked, even the battery. Battery life is incredible for a 2.0 battery, all day for our work. I've also used mine to install a fence, not as quick as the 18v DeWalt but it gets the job done. Even 3/8 screws.
Pros
