Overall this works pretty well. I was using a waterproof ipod shuffle which I loved, but I don't have the computer with all my music on iTunes anymore, so I've been listening to the same playlist for 10 years lol. I wanted this one so I could listen to spotify. Despite the cons listed below, I would purchase again.
A few cons:
1. The spotify app downloads directly to the device, so navigating it is hard because it is teeny tiny. They give you a stylus to use which helps but not ideal. They call it a micro tablet, so it functions like one and you don't need your phone at all. I wish I could sync it to my phone so I could navigate spotify there with my bigger phone screen and just download the playlists to the device.
2. It is really hard to work the volume buttons while you're in the middle of your swim. The volume and skip fwd/bkwd are the same and I usually skip a song when I mean to turn the volume up.
