Have the telescopic arm directly ordered with the squeegee, because I want to clean and dry the glass roof of my conservatory. The possible adjustable angle and length of the telescopic rod are perfectly adequate. When cleaning the 15 degree sloped glass roof rather the necessary arm strength is the limit, so I will not get along without a ladder. This aspect does not detract from the product evaluation, but there are leading to deductions for me two aspects: o Spannarretierung: The Spannarretierung is due to the apparent intention of the developers to make the arrest as narrow and small with a short lever provided with two recessed grips. Opening need a little strength, the plastic seems sturdy enough for good. The closing of the lock is Subobtimal. The opening force must be applied to close. It is (unfortunately) twice succeeded to pinch me the palm of your hand. Dissolve Liese this problem by extending the lever stroke, therefore, a longer lever. -> Minus one star. Excerpt protection: I have the same "made it" in the first elongating the telescope to extract protection to overcome. Does not disturb the stability of extended telescope, but now rattling the bar, since the stopper rattling the handle. Unfortunately, the plastic is welded so that a repair is not possible. Solution Stopper make stable. For the weak stopper minus one star. Price and function otherwise okay, so three stars.
