I rarely write reviews, but these cables have impressed me that much. Shortly after I bought these I landed in the hospital. I took the 10 foot cable with me. Over the 4 months I was there, the cable was well tested. It was pushed, pulled, knotted and tied, accidentally yanked out of the wall socket many times, run over by the tray table and caught up in the bed(which I kept it lightly tied to. ). I was moved to 7 different rooms on 3 different hospitals, each time the cable was quickly crumpled up in order to move. I’m now home and the cable is still working perfectly.One handy feature of these cables is that they work for power AND data. Most magnetic connect cables can’t do that. It saves having to remove the dongle from tha phone’s power socket in order to use an old style cable.The hinged connector on the phone end of the cable means the cable isn’t in your way if you need to use your device while it’s charging.As for speed, I have nothing to compare to, but my iPhone 13 charges in about 2 and a half hours.With one 10 foot, one 6 foot and two 3 foot cables, you’re pretty well covered. There are also 2 dongles for each phone type so you cand share as well as mix and match depending on what brand you own. I’ve bought more as gifts be cause they’re a good value. You can’t go wrong with these cables
