Best Bluetooth OBD2 for M235i?

Thought this would make for a good thread -



BT OBD2 for our cars - which is best ito ability / reliability / etc...?



This has best rating but most $ (accord to Amazon)



ScanTool 427201 OBDLink LX Bluetooth: OBD Adapter/Diagnostic Scanner for Android & Windows





Others that seem good to decent and better priced -



BAFX Products - Bluetooth OBD2 scan tool - For check engine light & diagnostics - Android ONLY



Saddle Super Mini Bluetooth OBD2 OBDII Scan Tool Check Engine Light & CAN-BUS Auto Diagnostic Tool for Windows & Android Torque (Blue Color, Super Mini)

Anyone with experience in these? Would be great to know more about them?
