Got it in the mail yesterday, haven't had a chance to play with it yet.

For those who has the Carista, any Pros/cons? feedbacks? Easy to use?

There are several AW threads on the Carista app besides this one. You could do a search for lots of info. To answer your question, it is easy to use and inexpensive. The downside is it can't do everything that a VCDS can. Think simple screwdriver vs. a power drill that comes with a vast array of screwdriver bits.
