Another thing worth pointing out about the Nulaxy USb flash drive is that the Lightning connector extends out quite bit. This is great as it means, even with a protective case on you'll be able to hook the drive into your iOS device without having to remove the case. Another plus for he Nulaxy flash drive is that because files aren't stored on a cloud it means it doesn't take a long time to download files back to the iPhone/iPad, which is very convenient!
