Product review (1 stars): Very flimsy
Very flimsy. The tube is constructed of thin aluminum - and is subject to easy crushing or deformation. By way of illustration, if a book was placed on the tube, it very likely would be deformed - and if creased, hard to reshape. I have two of these devices and the anti-pest screen on one would not stay in place. Fortunately, using the parts from the two - I was able to form a usable device. Not recommended.
