Verified Purchase(What is this?)
This review is from: SanDisk SDSDQUA-128G-U46A Mobile Ultra microSDXC UHS-I Class 10 Memory Card + SD Adapter + Memory Zone Android App up to 30 MB/s read - 128 GB (Personal Computers)
I bought one of these for my Lumia 1520. With the Windows Phone 8.1 update you can now run apps from the MicroSD card and so far I've had zero issue with it, they function just as they would from the internal storage.
It's hard to imagine filling up the whole card but it's nice knowing I won't run out of storage space and won't have to constantly swap cards.
If you can afford it I recommend the purchase, I was lucky to get one when it was priced £80 and I don't regret it.
