Vent Mount - broke down on the first installation attempt

Yes, unfortunately I had to throw away this product after the first growing trial. When I installed the holder on my ventilation in the car (Skoda Fabia) and they wanted to make out again, she was no longer get off. You had a rear clips (of a wave is formed) press / push up to them abzubekommen again, this is unfortunately broken and fallen into the ventilation. The adhesive pad is quite ok and I use even when not in the car. Through this broken clips there are of me even 2 stars. Here, the processing should be again reconsidered something. A simpler mechanism would probably be helpful. I have not even "use of force", as a woman you're there anyway careful but the clip is broken ..
