Nilkin case:
+ Thin and shapely
+ Good grip on the back (the '' smooth '' LG particularly important)
+ Keys are exposed
- Short life, the first cracks already after 1 month and which is handy although I never dropped
- 12 Euro expensive
Numbi case:
+ All around protection, not only at the sides and the back, so probably better protection against the weather
+ Robust
+ Is good grip
+/- Visually, it lets the mobile phone look slightly larger, but it looks nice from the back of sporty.
- Not quite as good grip on the back, but significantly better than without.
- Leading to blistering at the corners of the screen protector, although does not really bother, but looks a bit ugly.
Conclusion: If the case is not as fast Nilkin tear ('m not the only one), I would stay there again access. But as the Numbi is the better and cheaper option.
