Its easy to be opened by any one. The Velcro feature is great and there is even added Velcro for headphone wires (when I forget to charge my wireless ones). Love this brand Wait to see how long they will last. Jai en suite changé de caisson, jai pris un avec un flux dair élevé, toujours pareil. The size, The built, the quality, everything is TOP NOTCH. Its a little too big but I think if I went down to the 9 1/2 if might be too small. Wouldnt be of much use in a clothes shop, the extendable brackets are not "heavy duty" but it works well at home Deo leider mit Aluminium. We are trying to stretch them.
