The small footprint, you can install this on any machine and be working within hours. For those who are used to using Concordance but are tired of the lack of features, this tool is what you need. You can process data and load it straight into a database, this is great for a small review. You can unitize documents on the fly and produce documents with ease.
The record limit is a bit off putting, also the fact that this is not a SQL type database, so you have no backdoor to your data. I dislike that features that are available in Eclipse SE may not be available in the full scale offering of Eclipse.
If you are looking to work with an eDiscovery tool but have off put by the high pricing and sheer complexity of the interfaces, then this software is for you. You can process documents and load right into the platform. This includes some metadata extraction, OCR, and even tiffing if you have the correct setup.
This tool has allowed us to work with smaller firms with smaller budgets and still give them top tier service and support while maintaining a level of convenience that our clients have been accustomed to.
