The delivery took a long time to 4 weeks, but I had not made sure that the reader will be sent from China. Ok, a long way. That's why I had the package also pick up at customs, what with the printed order from Amazon was not a problem. But just a nuisance because of the customs has no employee-friendly opening times. The Reader works fine on all Mac OS devices, only iPads and iPhones refuse to cooperate. The Device of the iOS devices is easily recognized, the use is stopped but with the indication that the reader takes too much power. Understandable, but a pity, because especially for use on the iPad I had bought the Reader. A small indication of this would have been nice. Otherwise the reader 1a is processed feels valuable and images can be read really fast CFS. If the problem with the iOS devices would not, I would have given 5 stars.
