As for the DIY I am a layman or "average consumer". I am certainly not an expert and can also write the review only to the effect. The technical data can be found in the product description. Unfortunately I have no way to verify this. So I can only my subjective experience lay rate. The performance of the impact wrench is powerful and effective. Even thick screws are screwed easily. The illumination by the LEDs 3 helps especially in something darker work atmosphere. So you can see exactly where you work. In addition, the cordless screwdriver really sits well in the hand and is (for a battery-powered device) is not too difficult.
Even as a layman is the velocity to regulate well in the position so that there will be no unpleasant "accidents" or scratched surfaces.
The free processing of the device is very high quality and durable and because of the color I find him personally a great visual impact.
A definite plus is the case, in the machine and battery charger and battery itself can be stowed easily. So everything stays together in one place, saving you the hassle of searching. Only when using multiple devices with a battery, you should think about a permanent place for the storage of the battery and the charger!
For our budget this device is definitely the start of a new "collection devices" because some other devices of the series are very interesting for our budget to purchase and no extra battery they are also less expensive to save without sacrifice performance! Very well thought-out system of company Einhell. Therefore strong buy recommendation.
