Hi,
Thanks for your comment and we're sorry to hear you have experienced our product like this. We have immediately shipped you a replacement to make up for this loss.
As a sidenote, next time when you have applied the Spyslide, firmly press on the cover as well, and wait 3-5 minutes before you try to slide it. That way the Spyslide attaches nice and solid :)
Let us know if you have any other questions or concerns in the meantime.
