Cons:
None that I've run into, they respond quickly and operate well.
Involvement:General (knows how to use it) - Ownership:1 week to 1 month
Pros:

- Rather cheap for all the functionality provided.
- The little ribbon cable used to chain several modules can be used to connect the Arduin...
Cons:
- Build quality is rather average.
- Finding datasheet about the chip used is very difficult.
