Practical, but also long-lasting?

Basically makes the charging plug what it is - namely my cell phone while driving charge.
He does this also to a sufficient degree, if I use the phone as a navigation tool. It is nevertheless achieved a load success.
Practically I find with this is that you can bring the cable to the desired or required length and disappear when not in use all over. So you have no disturbing cable spaghetti in the cockpit and can store the compact device well.
Whether the charging capacity also is still sufficient if you connect another device via USB connection, I can not judge because I have not tried this.

Up to this point I would therefore awarded 5 stars!

But unfortunately, there are in my view two major drawbacks:
1. The representation in the white-colored surface is a blue glowing indicator lamp in use. Control is all well and good, but just at night, I feel both the luminosity (very bright) and the surface to be disturbing.
This problem can be a 'no time', so that the luminous area of ​​mine is gone.
A smaller lamp would have done so well.
2. The model used by me refused after only a few uses his service.
Since it is a 'cheap' Preßproduktion, you can not take control of the plug apart.
Only the tip can be unscrewed to replace the built-in backup.
The fuse was intact in my case, a cause I could not see.
Ultimately, it turned out that the male is suffering from a 'loose contact' and 'revive' by back-and-forth turning leaves.
That's not necessarily nice, but I can bear. I just wonder how long by holding the plug ...

CONCLUSION:
A really practical plug for relatively narrow money, but with regard to the life I do have my doubts!
