Hi guys (and gals)... I was wondering if anyone here has experience with the SanDisk Wireless drive or the Leef? I am mainly interested in these devices for music. I have a 16gb iPhone 5S and I find myself often looking through to find what I can delete because of storage limit. My music collection is fairly small at around 4.7gb, but that's still a big chuck of the device. I have looked at some reviews and but havn't been able to really find this answer. Since I am mostly concerned about music, how is the music playback for these devices? I am using Tuneshell for my music player as the stock app is about worthless (since iOS7 came out). I am pretty sure that the stock app nor Tuneshell will be able to playback music from these devices, and that I would have to rely on the music player that is in the device app. Is that correct? If so, from a usability standpoint, or either one any good? The video tutorial I saw for Leef looked like it was extremely basic,.... I didn't see playlists, etc. Thought??
