I currently have the Invisible Shield on my device and it works great, except for one problem... I dropped it and rocks were able to puncture through and scratch my torch... I found this odd since a "knife" cant puncture through it... I ordered this last week and put it on today it feels a little smoother than the Invisible Shield but we'll have to wait and see how it performs. Their giving them out for free too right now!! just pay shipping and handling which was $3 for me! Stealth Guards
