I'd be wary of this.
1. Windows only. Not even Mac support, let alone Linux.
2. It's not actually a scanner. Inside it's a cheap digital camera with a cheap lens, aimed at the slide/negative with a light behind it. You can achieve the same thing for a lot less by screwing a good old fashioned slide copier to the front of your own digital camera. Search eBay for "slide duplicator" or "slide copier" - you can find them for a few quid.
It's probably better than my ancient 8-bit SCSI Minolta Scan Dual, but don't expect results comparable to any more recent serious film scanner from Minolta, Nikon etc, or any real control over the output image.
