The pruners is easy to assemble and operate relatively quiet and torquey. However, already noticed during assembly that the extension only with a single small metal knobs (about 1 cm away from the pipe end ...) engaged in other pipe and "secured" is. My evil forebodings should regret to confirm the operation. WHILE using dissolved Widerholt this "assurance". The extension incl. Saw was even twice with the engine running completely out of the other pipe. Only the power supply cable which extends inside the tube, the units still held together. This is dangerous !!!! Completely incomprehensible to me how such a thing can be sold and also receives seal of approval!
Previously, I had actually made passable experience Einhell devices. But this product has earned in my eyes no star, rather a (sawed) thumbs down ....
