I have been trying to reduce cables and also be able to re-use back my old cables especially I have a lot of 30Pin cables for my old iPhones. The 8 pin lightning is too expensive thus this adapter is a welcome sight. It works perfectly and furthermore it can also support the micro USB.
Unfortunately, when I use a case with my iPhone 5, it does not connect well enough to recognise. However, my iPad mini works okay.
Need to design something which fits iphone with cases.
Recommended if you have a lot of old cables to be re-use!
