Does exactly what it's supposed to do. I got these for my 2 kids fire tablets and they both work great. Remember when you paste them for the first time it will most likely say they are not compatible because they need to be formatted first which the tablets pointed out and after clicking on the notification it will take you there, where to go to easily format them. . Also note that I was logged into my parent account at the time. So if you insert cards and you're on a child account, you may not get notifications and may not see connected external storage. After formatting the card, you can check the storage options and move all apps and data to the external card with one click. I recommend this because in my experience, at least, my kids' tablets slow down the closer they get to full internal storage capacity. Try to keep it as open as possible.
