I bought this for my E-PL6 recently and it works quite well. What it offers is an ability to upload pictures to a Bluetooth device that allows file transfers. My Android phone works well with the PP-1. There are some caveats to this device, one of which should be fixable via a firmware update.
1) You can only transfer files individually. It would be convenient to transfer them in bulk, or even automatically, like my Android phone does with my Google+ account. But at present (2014) it does not allow this.
2) The included documentation does not tell you how to set up the device. Those instructions should be in your original camera documentation. My E-PL6 documentation has these details.
3) The menus for the PP-1 are a little non-intuitive. The "Please Wait" menu item is to *receive* images from a paired device. You send from the camera to your paired device on individual picture pages, once you press "OK" the item should appear. Strangely, the PP-1 has its own memory so you can send from the camera to your paired device, OR you could send from the camera to the PP-1 (still stored locally, but not on your SD card).
