Hello Everybody, I am astounded by the small card reader. It works with my iPad 3 and my Android devices properly. First time the latest firmware update from the Kingston Homepage loaded (if it should not be on the card reader top version 1.1.3.4-). After the Kingston MobileLite app downloaded from the Play Store / Apple Store ..... and there you go. If it should come to Verbindungsabrüchen with you, you can switch to the Mobile Elite app connecting channel ...... after that it should be super fold. The card reader funzt also wonderful with the GoodReader or Total Commander + LAN (Windows share) plugin. Various Video Player also work with no problems. Copying a 1GB large movie file (from the smartphone to the card reader) will take about 6 minutes. The streaming movie files to the iPad works without stuttering or dropouts (eg with the AV PLAYER HD). The copy of the card reader on iPad (GoodReader APP) works perfectly well. All this is of course on the Android devices .... the right apps provided (eg any file manager). Have all not only with SD cards or USB sticks but also with a 2.5-inch 500GB hard drive and it works. The wireless range is really great .... but that is of course dependent on your equipment used. On the homepage of Kingston you can down load a complete user manual and everything there is again well described. Streaming MP4 / VOB / MP3 / AVI FILES everything works very well .1080p files I have not tried yet. The battery life of the card reader is of course dependent on the load of the card reader ..... if you simultaneously accesses with one, two or even three devices on the card reader. I think of 1-5 hours is all possible. I give this great card reader 6 star ..... if only for the special price of only about 28 Euro. I almost forgot the size ....... the card reader is about the size of an iPhone 4 and weighs about 98 grams. I am totally thrilled.
