I got these a few days ago. Of the 3 cables, 2 are constantly being disconnected and reconnected to the charging power, or they need to be laid down and not moved. The third works a bit more stable, but not well enough to cost $25. My parents have another brand of magnetic chargers. So comparing them to this one I would say I like the strength of the magnets and the type of cable. . I don't like the round shape of the inserts, it would be better if the inserts had an elongated hole shape so you can use them with a phone case. I also don't like that my phone is still at 8% after 4 hours, it just isn't charging consistently enough to actually extend the battery life. fully boxed or ported, yes I've tried different boxes and ports, none works better than the other.
