Good idea, implementation flawed but very good price

Product comes beautifully packaged and counteracts my expectations quite high.
Unfortunately the keys are out very far, so they can be safely pushed into the pocket (Since a trip that requires a long press, that's probably not a problem)

The included app is (unfortunately) held with two windows quite simple.
Once the Find function, which unfortunately does not work properly: If the cell phone out of reach of the product, also rings (+ ringtone you can choose!) Is not with me, if you come once again within reach.
And even the very basic camera function: triggering, or zoom in / out using the +/- buttons.
Unfortunately, the auto focus can only be set from the phone and is then Fix.
Warning: There is no "anti-Lost" feature that would trigger an alarm when the device goes out of range.

Have tested it with two phones.
One would have Bluethooth 3.0 and the other 4.0. But can not guarantee it.
The behavior is the same. Maybe so both phones are not entirely compatible.

Total 2 star, because the idea is really good and the product a quality image. Unfortunately, the function is not fulfilled for me, or only very limited.

Perhaps the App is adjusted, then the product can still really be something!
Here, the use of the +/- keys should be changed. I know a few that use the zoom, especially if the idea is that you can not hold the phone when triggered in hand and if necessary the screen does not see. And a real "Anti-Lost" feature would be great.
