I did a search, but nothing really jumped out at me, so I thought I would start a new thread.

Does anyone use an OBDII reader with Bluetooth for an Android phone or tablet? If so, what type do you have, and what are the pros and cons of it? I recall reading something about a particular type here, a long time ago, but I don't recall, and wasn't successful in a search, finding it. I have a code reader, so I'm not looking for something that just displays codes. I need real time diagnostics.

I am primarily looking to get one of these for another vehicle that doesn't have a temperature gauge, but rather just an idiot light. That vehicle is prone to the coolant recovery tank splitting, and by the time the idiot light comes on, the damage to the engine from overheating is likely already done.

I might also use this device on my T4R on occasion, so I thought I would ask here. Lots of DIY folks on here, and I haven't yet found a good forum for my other car (Mazda 3) for DIY stuff.

The primary things I am looking for are something that has a pretty low profile, so it doesn't get sheared off by my knee, and it also needs to display engine coolant temperature. I'm hoping to learn what the latest and greatest is.
