Excellent high-end wrench. Flow rates required, very reliable retraction system. Small precision: strangely, the key is initially formatted as FAT32, which prohibits the transfer of files larger than 4 GB Before anything else, so start by making an NTFS formatted (Windows, right click on the drive => ". format "=> choose" NTFS ") Amazon Price ultra interesting at the moment, 115 (against 175 in some hardware site).
