Ni, I am pretty sure that it is not. If it is the one that I bought, it did not support audio - i.e. I could not use it as an adaptor for an iPhone 5 in my Bose speakers. I have bought one that looks exactly the same from Curry's/PC World (much more expensive) and that works fine.
Yes it is , expensive for what it is but it saves buying all new docking stations and chargers ,so yes a good buy,there are a few people that have problems with it and there docing stations bur I have a blueray player that has a docking station , a Lanntec and Bose that workd fine m its just not for video only audio
Its unclear. It seems to be sold as an Apple product on the Amazon site but comes in a clear plastic bag (no branding), not a box, and only appears to charge my phone. It doesn't work in my speaker system. I was very disappointed with it.
