Good idea but not a good implementation

Negatives:
- No installation instructions, but at least pre-course.
- You need a bit of skill to get it all together properly.
- My keys are seemingly too big, I can not from those Arrange against each other for the part is quite simply too small.
- A very high price for the bit value. The screw is only secured only by two rubber rings. Without this, the screws after a short time.

Positives:
- Great idea
- Very easy
- Screws for different number of keys available
- An extra carbon part for the car keys available.

Conclusion:
I sent it back because it through my excessive keys just bad looked when the crisscross out there hanging.
Whether that's enough with the rubber rings in everyday life in your pocket so that does not solve anything, but I can not judge.
If something big and something better secured against loosening is the thing, I'll try it again, so I could not use it unfortunately.
Certainly very good at smaller keys but.
