Warning for Mac users: The device contains in the version offered here AV176U only Windows software. The mentioned Mac software EXCAT ScanLite SE is obviously a special sales variant for Mac (probably AV176 +) reserved, but which I never could find on the market. If you already have a scan software for Mac that the device supports (eg. Exact Pro), or is willing to acquire this extra is, recommended the device, seems durable and inexpensive.
