This is my first deal so be kind
This device is the A02 and the predecesor of sandisks wireless pen drive
technology A03 sandish wireless pen drive and A04 wireless stick
however the price is way beneath what both those cost you can also get the
16gb version for 9.95 but since it comes with an SD card you might want to
swap in your own micro SD with an SD adapter and save 2 GBP. Please note you HAVE to update the firmware and the old company actively blocking this as this device is support closed a few years ago. theres a dropbox folder with the most uptodate firmware on done by a customer before maxell went bust.
I have used this after updating the firmware with a 200GB micro SD from my m5 phone and it had no problem reading it and its a xc tech card
It is my belief that logically it should be able to read a 512gb SDXC card although I dont have 200GBP to prove it.
It also allows you to stream to an iphone so you dont have to use itunes
just put your music in one folder and download the airstash app.
You can also connect manually and enter the intranet address supplied to get access on a none android or ios device
