What makes it great, price is justified.

I understand why some people think: so much money for a bit plastic, I also tended first to four stars but after the first test but there are 5, even if it is plastic, it is total quality. Robust design, no protruding ridges and I'm not worried that it goes straight broken in 2 weeks. First concerns the system could come loose from the strap disperse at the first clipping on, the system is ingeniously simple, versatile, stable and effective. Buy recommendation!
