I really wanted to like these cables, but we bought these to avoid a repeat of my daughter breaking so many standard cables. She has autism and has to have the light and motion from the screen to relax enough to fall asleep, but the twisting and turning makes fixed cables break near the connector. We were hoping the magnetic 360 cables would allow that motion without breaking. however each of the three cables I bought lasted barely a fortnight each. There's no physical damage but it seems as though the mobile connection points just fail through wear. My suggestion is to increase the testing cycles and thicken up the contact sweep, or make it out of a harder copper to increase wear resistance. Broadening the sweeps and allowing a bit more play would also minimise the possibility of contact trenching, again, increasing the wear resistance. They're a great concept but need more development.
