Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
It works fine and it's very cheap. As soon as I hooked it up properly I could instantly begin sending and recieving data using my phone. You should check out some instructables on how to wire this properly. http://www.instructables.com/id/Success-Using-the-JY-MCU-linvor-Bluetooth-Module/ is a good one.
Cons:
No manual, no datasheet. Plus, the RX pin needs 3.3 volts so you need to build a voltage divider by placing it between a 1k and 2.2k resistor.
Other:
would buy this again.
Bottomline:
for this price you can't go wrong with it.
