I had previously ordered a different connection for my power bank and needed a new cable for my iPod and iPad. These are brilliant, they charge the device's quickly, transfer data quickly too and appear to be excellent quality....or so I thought...they keep snapping in the device. Luckily a good pair of pliers retrieved it. I'm not impressed. I'm not using them anymore. I wouldn't tecorecomthese, if your product doesn't stay perfectly still it'll snap.
