About Reactive protection without "protection" in front of protection

The application of both parts just went, although the upper glass can not be completely apply without bubbles. But that was not written too suffice.
DC after 6 weeks of protection was then also used - involuntarily, as elsewhere in the situation my second camera tilted by a few degrees, and pressed more on the rim of the glass as it fell.. The result: about 2x2mm crumbled place in glass, two through cracks through the complete protection. As has my second camera, which is provided with a cut cell phone screen protector, already intercepted more powerful shocks, without anything happening.
As the destroyed protection was not bad enough, I was able to deal with the rest of the day with the crumbling glass. Because even if the initially formed micro splinters were removed, but gradually came more splinters to which I then also found in the face.
Here clearly missing an overlying film, which prevents splinters (Chen) will be lost - because the worst may backfire.
And no: Not in every situation you can remove the protection immediately, even if it would have been quite reasonable.

Conclusion: For the price and handling, there are two stars. If the protection bit more resilient, and would not shatter at the slightest pressure or shock, I would be even more valuable. So this protection no second acquisition me, however, is worth it.
