I bought this one on 7-21-2015 and it works for me.
https://www.ebay.com/itm/V2-1-OBD2-B...-/290941249230?
Amazed the ebay link is still good to it.
That said there is some differences in the description and what my receipt email shows.
The one I bought shows to be a :
V1.5 ELM327 OBD2 Bluetooth Car Wireless Scanner Diagnostic Tool for Android
The one on the ebay link now shows :
V2.1 OBD2 Bluetooth Car Wireless Scanner Diagnostic Tool for Android 48VO
But that is clicking on the link in my receipt email.
