All I can say class part with lots of power and all that a 2nd battery is very quickly. I immediately fell in love. Build moment a prefabricated house (interior design) and you need a screwdriver of what endures, 500 screws are as nothing in the day, 55mm drywall screws coarse thread no problem for disen screwdriver. Battery holds long, all in all, I can only recommend it ..... keep it up Metabo. Have I still the Metabo Bitsatz risen sitting properly and working class with the screwdriver, good bits are natürtlich also the A and O. I hope I have helped in the decision, especially if you build a prefabricated house and do the interior work himself. Highly recommended is still a drywall screws with a stop for plasterboard walls there by Metabo ....... greeting
