Previously had a LG BE06 Bluray burner (external drive). None blank Bluray he could burn. Katastrofal! Then I read the reviews from Panasonic UJ-240 BD read here and can only agree with the positive experience. Both USB cable connected device detected immediately, first BD-R disc burned by Platinum, no problems! After a blank Verbatim - also easily identified and fired. RE blanks described also immaculate from Maxell and Platinum. Work that these blanks was important to me because they are mostly to get the best. Panasonic blanks run anyway easily. The drive is quiet, the housing flat, lightweight and durable. Panasonic label is missing. Is annoying, just in case is pending a resale The only drawback: The CD's you have to press pretty doll into the case at the hole. Even taking out a little hard. But if you want to easily burn Blurays from different manufacturers without ever reading bug reports and throw away some, highly recommended! Impress even the size, because you can easily tuck this external device to the notebook case. Ideal if you own laptops without optical drives.
