This fit perfectly in my Motorola Droid Maxx2. I'm able to save data to it without any problems (you will need to set your phone to store data on the SD card  instead of the internal storage on the phone itself). So far, no problems or issues - it just worked OK right from the start. Will post an update if I have any issues with it.  Just remember that what you can store on the card will be determined by the app you're trying to download,  your phone's OS and the phone itself.
