I have now used it a couple of times and its awesome. Aufsetzen, ausrichten und den Hebel runterdrücken. Ordered these for my daughter. Its too late to return so now Im stuck with these ugly flip flops. I keep losing my keys, but more importantly the many remote controls that we use, I placed the finder in a central location and whenever we try to find something we just click on the corresponding number on the finders remote et voila! I dont really like it because of the bulk and noise of velcro ripping open but its the only case I trust to be outside of a bag or pocket. I need to work on that, but I think there is an easy fix I will work on later. Ich kann sie nur weiterempfehlen. Its pretty good. They happen to cost just over half of what Crocs charges for similar style of clog.
