1) It may be "highly customizable", but that is only from the backend/style sheet perspective - don't get this module if you are looking for something that has an easily configurable interface. The interface is very limited.
2) The "cool" looking examples on their site are not free. They should also tell you that up-front. When you buy the core module, you get 3 basic templates that are pretty undesirable. To get the module to look like what they showcase on their website you have to purchase additional templates.
There are other modules that are capable of doing more and are cheaper or even free.
This is likely a great module for those wanting extensive control and willing to do backend style sheet/template creation, but it is not an easy plug and play module that will give you great results.
