From his page, to quote roughly translated: This PS3 CFW is installed directly into the NAND has been tested in different models of console (FAT and Slim, reported in the main post) and without any bricking or similar problem.
The testers have reported a high stability in the CFW and the same compatibility with games that could be obtained with different dongles.
The main core of the payload is based on Hermes, also has some features of PL3 and supplementary code and improved by Waninkoko.
Attempted to create an application that enable / disable the payload, so that after leaving a manager backup Blu-ray was functional. After some testing has not been able to be operational, it would be desirable for the various backups managers were in charge of implementing such functionality or may be added in a later CFW.
