Before I went abroad I bought a set of 3 of these 3m USB cables. I assumed staying in places where the outlet wasn't within the typical 3 foot charging cord length. Two of them have been working every day for more than a year without any problems. While we are cautious users, both ends of the micro connector have taken falls, but this is not a fault of the cables or their design given the amount and type of use and wear and tear they have experienced. directly to our previous order to order a new set. Very good value for money.
