The balcony networks serve their purpose, that neither baby nor toys can pass through interstices. The networks hold so far good, no cracks or similar, error to see. The design is pleasantly unobtrusive, the networks are still transparent. The only drawback is the attachment, which is a little more friemelig. The enclosed mounting elements are plentiful and work through the smooth lines you have to bind the knots but with care and check several times. Furthermore, it is quite cumbersome to thread these cords through the narrow meshes of the net. However, the attachment is indeed a one-time process, so only minor deductions.
