With iPad, iPhone, Asus Slate B121 no problems. But this is not my purpose this keyboard as my Slate already a Bluetooth keyboard and mouse has, and I do not need to iPad and iPhone that.
Unfortunately, the link does not work stable with OpenELEC / Kodi on a Raspberry Pi. As soon as the keyboard goes into standby, you must be re-linked. This is for the remote control of a media center a "no go". Even after restarting Kodi the keyboard is no longer coupled.
The service of CSL is excellent! So if the purpose is not OpenELEC, then I would recommend the keyboard for ultra portable applications!
