I regret not buying this wi-fi SSD. This is a great product which I could no longer do without. I itilise this hard drive with my iPad to watch movies. With this hard drive that reads many formats (avi, mkv ........) need to convert the formats of your movies for playback on your tablet. It has a capacity of 128 GB which is quite correct. It has a long battery life in terms of battery. Its small size (size of a credit card to a thickness of just over 1 centimeter) makes its easy transportation in the pocket of a garment. Its use is very simple. I have absolutely no complaints about this product that perfectly meets my expectations.
