After I had initially ordered the 453 screwdrivers and this gave work after a few hours, I have decided for the 459. Topp! Almost good that the previously ordered 453 was defective. This device is high at least 2 classes better, not least because of the brushless motor. The battery with 4.0 Ah have an almost frightening persistence, and even at the highest requirements and also cold working conditions. Subsequent charging time is about 36 minutes. From me there is therefore a full purchase recommendation for this device. So makes work fun.
