First I have to write that this is a very well thought out and high quality product. No China garbage from plastic but of high quality anodized aluminum. The system is well thought out, good materials used, easy to assemble, easy to "operate" and certainly very durable. ... Unfortunately, there is a point of I noticed until months after the purchase of makes me very questionable. After my phone charger (original Samsung) has sporadically not loaded, and my universal charger has mostly not working, I noticed that it is because that the contact surfaces of all chargers are only at the pin tips, and not as a standard safety plug the entire length go. This means that I "too far" in put the Chargers in the Evoline and it just or just do not have no more contact. (For me it is a bit strange) Most importantly of all that it can happen that in poor contact is a certain "brizln" to hear. Quiet but ... what actually is that the current can flow badly and actually already held "mini-overs". 'D not be surprised if that is sometimes hot and burns easily. So a safety issue. : /
