I like that it has the ability to ingest any source of structured or unstructured data into our system so we can use our RDS instance as an ETL tool. It's easy to set up with minimal configuration needed. You need to have some experience managing AWS instances but once you do things are pretty straight forward. We used this product mainly because of its ease of setting up and configuring. There is nothing really specific about what they offer. If your looking at other products specifically designed for ETL then there may be better options out there. Our main goal was to get data ingested directly into Redshift without having to go through S3 first.
