They arrived quickly and the cords are well made. Looks nice. I feel great. But. 1 of the long cables does not charge OOB continuously. It's never fast charged, takes over 5 hours to charge, but charges just over an hour on a different cable from the same pack. So it could be a manufacturer error. Received 2 packs of 4 cables - so 12.5%, OOB error rate. Then, after about 2 weeks, one of the magnetic charging heads literally fell off the cable. Mistake #2. The final problem is that the connectors are not wired in series. They attach with absolute ease. The magnets are strong. BUT, they must be properly aligned to make a connection. This usually just means twisting the connector a bit. In any case, at a price with 25% rejection, they are expensive and seem unreliable. Nice. But unreliable.
