I work in a furniture factory. The main tool is a screwdriver. I am very pleased with the tool. I ordered this time the next model DCD 791d2, with corrected backlight and lighter. Different pros: 1. Price. Ideal for a professional instrument. 2. Weight. For an 8 hour working day, the hands get a little tired, but you can work. (Before that, I used hitachi and interskol). 3. Ergonomics. Comfortable rubberized handle. The screwdriver is perfectly balanced. 4. Battery. Even after 2 years of use. The battery lasts approximately 2 hours. And the second charge takes only 30 minutes. In the first year, it was enough for 4 hours of continuous work. Got cons: 1. Inconvenient backlight. At the right moment, nothing is visible because of the cartridge. 2. After a year of use, the button periodically stopped working. After 1.5 years, she completely died. It costs about 1500 with a replacement.
