Completely hands-free review. It all just happens in the background, and you can review the state of your code at your convenience. I prefer the cloud based approach compared to a local installation of a code format tool, as its constanly being improved without having to deal with an upgrade on your machine.

The only downside is that there is a cost for the service, as compared to a buy-once local installation. But that cost is small compared with the value obtained from the reviews. I also wish they had a formatter for c#. Review collected by and hosted on G2.com.
