In itself, I am satisfied with the device. Unfortunately the UJ260AF is equipped with a so-called Rip-Lock (if that's the case with UJ240, I do not know, only you knew that beforehand not what you get here). That means Blu-ray videos can be saved just by 2X read rate. Because I feel that as a nannying, raise no firmware that corrects this and that one of my main applications, the unit with 2 stars is deduction still well served, because it reaches only a fraction of the advertised speed in certain applications.
