More than useful

I'm actually not a big fan of hard or soft cases. It usually takes me something even not really.
However, if the Lumia 830 knows or even owns, will certainly have learned that the keys were attached to power and the dedicated camera shutter extremely unfavorable on the right side of the phone. A stroke of genius Finnish mobile-engineering!
When handling the phone so frequently is involuntarily activates the camera or the unit would like to be shut down.
Even those with a universal car holder had his fun, know what I mean.
And here this hardcase comes into play ...

The delivery took place in a timely manner within the announced period.

The case itself is made of ABS (?) Plastic with velvet rubber.
The cut-outs for keys, camera and speaker are precise, burr-free and precisely.
If the mobile phone "clipped" in the case does it as well as to not. The phone is secure and there is no play on the edges.
It feels comfortable and does not slip out of your hands. Time will show, however, whether it considers applied rubber.
Experience has shown that such a rubber tends to expose bare spots by abrasion and / or flake.
The inductive charging function is not affected by the case.
Overall, especially in view of the price, quality workmanship and a perfect fit.

As for the protective effect, I would not go over the bridge and say the falls are cushioned also from smaller heights of the Case. I did not try, but would predict due to the nature that depending on the angle and the underground nature of the case on impact by head of the energy and / or disengages from the phone and thus provides a non-optimal protective effect for this scenario.
More suitable as protection against scratches on the cover or the camera lens is why, in my view.

What has absolutely convinced me of this case is the fact that by now slightly recessed control knobs unwanted camera triggering is reduced to zero. The same applies to the use of my car cradle!
100% acquired Thus for me expedient and only for this reason.

Conclusion:

Those looking for a quite stylish case for a very good price without having high demands on the protective effect can be quite happy with this Hard Case.
Who a heightened need to protect his cell phone has compared to, is probably better off with a PU Case or a "Otterbox".
-Suffering Lumia 830 users that develop through constant camera tripping or inadvertently turned off cellphones destructive hatreds their phone over, this case was, however, warmly recommended!

Summary:

+ Very good price / performance ratio
+ Very good workmanship and fit
+ Hardly noticeable when worn
+ All connections and control panel easily accessible
o possibly (not tested) only limited protection from drops also from lower altitudes, depending on background and impact angle
