Great cheap option

Out of all the OBD readers this is the easiest to use. It may not fully work if every vehicle but it’s great at pulling codes. Worth it!

Simple and useful

Needed an OBD reader to monitor various things (particularly related to hybrid battery health, temperatures, etc) on a Prius (dashboard gives very little info).

The reader is effortless to install (plug it in under the steering column) and links effortlessly via Bluetooth to the iPhone.

Adding items to monitor is also nearly effortless with a long list of Prius specific items (and all the standard things for regular cars). Display options and choices are also easy/ intuitive to use. No manuals needed.

Only suggestion would be to input high/low ranges for certain items so that the displayed data item goes red (versus normal green) when out-of-bounds. That would make the app immediately useful during a roadtrip, minimizing distraction: you see red, you pull over and see what's up..

Try it, the iPhone Blutooth (low energy) reader is only about $35 (Amazon Prime) and the app is free. Super useful tool.

Terrible app and adaptor

Literal garbage app. Connects to LeLink but doesn’t display any data. No setting to adjust. Absolute junk. Will be returning the adaptor
