Some Nintendo games have the option of add characters in game, and this device lets of pick from thousands of those characters without handling the physical amiibo itself. The ease of use can be VERY easy, if just using the preloaded amiibo's. Getting into the file management on the other hand took longer than expected. It's not so bad if you actually READ THE MANUAL, but going in as a tech I assumed... The interface is effective, and surprisingly responsive, but could use some polish. The face plate came off from trying to pick it up out of the box. Minor glue issue and seems to be holding now. I have hundreds of amiibo's, and this little device has already saved time by not having to get up dig through them all.
Tips: Left and Right arrows are to move what's selected. Moving left right up and down, all use the Left and Right arrows. Up arrow is Select. Down arrow is Back. All file management is done over their website. Use your phone to connect, not directly with Bluetooth, but with their website.
