Hardware side: Remote control with backlight. The hard drive installation poses no problem, just unscrew 6 screws.
On the software side: Impeccable. Readers recognize almost all formats. It works without problems with my collection of MKV. Navigating the camera's menus is very fast and very simple. The device startup is not so fast that it (30 seconds or less because the time to search all film 4T). The system covers the film is superbly well made and great. This much for the files on the internal drive as those located on the external hard disk).
In short, a rating of 5/5 without thinking, I recommend without regret.
