Strong performance - never thread loss

Finally I have a trimmer in which I have never had a yarn break or tear, even with extensive and difficult work.
The trimmer can be down in the inclination adjustable, in the middle of the handle can be rotated (general course both firmly locked).
Through this adjustment can be the cutting direction in the inclination adjustable (from horizontal to vertical).
The handle and holder for the first hand contains the on / off switch and the same strain relief for the power supply. Unfortunately, I slipped out the cable a few times and the eye where the cable must be passed through is relatively small, there so that the cable must be crestfallen to it to thread. The handle for the second hand is adjustable in several stages and adaptable. Overall I am very pleased with the performance and the automatic line feed works perfectly!
Unfortunately, I can the length of the trimmer not vary I need to handle longer, so I have to work more in prevention and bend over, there's a point deduction (back pain can greet).
