Purchased 3 BoxWave lightning cables last year and they worked for a while. After Apple ios 7 released, none of them work from then on! My iPhone 5 will give me "not compatible" message and they just don't charge my iphone 5 regardless of how many times I tried. They are now 3 pieces of junks in my drawer and they wasted me $30 all together, could have gotten 2 AZ lightning cables instead. I don't buy Apple original lightning cable since it is way over-priced, so I am not telling you to buy original manufacturer cable, just look for other brands that will actually work and keep working even there is an iOS update in the future, AZ basic for example. At least AZ will back up its products. For now, I am staying away from BoxWave forever. I tried to contact Boxwave about how to get my money back, they just simply disappeared from Amazon for 7-8 months and now it is start selling again. Since it has been over a year, I am sure they don't even care about my complaint now. I think this is its nasty strategy, just sell a bunch and disappear while no warranty need to honor if its cable doesn't work and then come back and try to sell a bunch again! Be careful!
