I bought this product there are 2 months now, the possibility to access additional storage for my iPhone and my iPad WiFi is really great. The application is easy to use, better than iTunes !! Copy speeds are very good (obviously, it's an SSD) and especially the autonomy of 6 hours is very significant. I was surprised by its size, it fits in my shirt pocket and I walk everywhere. I have copied my whole repertoire without worrying about the size and what is practical with the Iphone. Similarly for movies on the iPad, and even more surprising, I have access to the files with the Iphone and Ipad same time !! In short, my only regret is having bought too early because now the price is very attractive. Recommended!
