But scarcely a difference a clear lack - No Customer Service

The application of the protective glass is very simple and is also slightly out of hand. Once aligned and a short tip to the glass, even the glass draws largely independently on the unit. The last blow to wipe with the supplied cloth away.

When operating to no restrictions arise. In my view, after the home button is even a little more convenient to operate by the touch of the protective glass. The camera is not cut, but it works without problems.
Operation Technically, it feels natural to like glass and is very pleasant.

Unfortunately, the glass on the edges and the speaker raises after a few days use without any particular stress.
The unit is located in a Case-Mate Tough Cases. This has massive air to glass and counteracts any distortion. Apparently the glue is applied incorrectly on the edge, the glass was applied centrally on the device.

The manufacturer was contacted to the effect. As soon as new findings are known, the review will be supplemented.

Addendum 04.18.2015:
The manufacturer was contacted, but has given no reply. For me, unfortunately, incomprehensible, therefore actually 0 stars. Not advise!
