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

Pros:
Good price, quality is ok. Easy to configure. You can easy found the datasheets in the internet. Module is very small but is easy to solder. Cheapest solution - buy it if you want to connect to devices with UART via BT.
Cons:
It's a slave module only. Module HC-05 can work as a slave or master.
Other:
Datasheet is minimal. Rx input isn't probably 5V tolerant. If you work with 5V tx signal from uC you can add a 1k series resistor and 3,3V zener diode to gnd from Rx pin in module.
Bottomline:
Great product with tiny size.
