The system works on the principle but it absolutely must not touch the phone. The room does not be alone. the magnet is not sufficient to bring the piece and the cable connected. Too bad the idea is good. I think I could use it, once I would adjust.
The version with mini cable 10cm is not better in "magnetic" and positioning ... but usable for a similar price I rather recommend the Magnector version bcp more expensive but efficient magnetically positioning and holding.
