The adapter is well made - that could well pass as original accessories. To my mind he is sitting a touch tighter in the devices than the original cable that already 2.5 years, however, is in continuous operation and is expected to be slightly abraded.
Both iPhone 5 and iPad mini can be loaded without problems (in both directions of the plug; no warnings) and a data connection to connect to a computer.
For me the ideal companion in Portmonaie if I once again no cable, but need - Micro-USB, there is always somewhere.
