Hello folks.
Just wanted to let you all know that I checked the QPxTool forum today and found that they have an updated version of their Plextor PX-755 firmware.
It is now up to version 1.08 (the same as official).
For anyone doubting their usability or "safeness" I can mention that I have been using their version 1.07 since it was released without problems.
Have not had time to test the new version fully yet though.
Find it here:
