My wife and I have used the ET16Plus for about one month now--And we have found it very easy and fast to use.My wife scans lots of foreign language books for reference and used to use a flat bed scanner (that has a nice feature that allows books to scan only open 1/2 way--But the flat bed scanner light and mechanism would wear out after a year or two). The CZUR used LEDs (plus 3x LED lasers) and pure electronics to take a picture for scanning--Hopefully, this will last a very long time.Much faster than using the flat bed scanner and no flipping the whole book to scan each page. The side light option is very nice for scanning glossy pages (turn off overhead LEDs).Software can be installed from CD or downloaded from CZUR's website (which I did, Windows 10 laptop did not have a CD Drive).Post processing (doing OCR and combining to PDF) was very simple, easy, and fast. Have done OCR for both Chinese and English--Pretty accurate (a lot depends on image quality of source documents). I have attached both a color glossy and black&white scanned documents at the end of the review. They were simple scans and I did not take any extra care or reshoot scans (black text on dark background near corners of page can be difficult to capture cleanly unless you play around with settings).Using the software takes a bit of experimenting and understanding how it was intended to be used. For scanning, You need to select scanning (can also be used as a camera to project on a digital protector for lecture materials), then you will be taken to the post processing screen. Then select Scan. On the scan page, you need to (upper left) setup the destination directory. Upper right choose Color/B&W/etc. for your scans. Then single page or facing pages. Now you can scan (I use the supplied foot pedal).Once you are done scanning (if you make a mistake, just write down the one or two image numbers to delete) and continue scanning)., close the scan window and you will be taken back to the post processing screen. On this screen (for example), upper right "select all" images to process, hit Export and PDF+OCR) and fill in the file name (note, the PDF document does not end up in the Image directory--but up a couple levels).And it will take a minute or two to process a 20 page B&W document into your PDF+OCR.If you made a scan mistake, on the post processing screen, you can deselect your mistakes, or select the bad image and use the delete/other editing options to fix the mistakes.Note that as you go back and forth between screens, you will probably get a warning that some temporary data will be erased--So far, I have not found any downside to this message.If you scanned your data in one session (and turned off computer before post-processing), you have to open the program/scanner/scanner (scanning screen) and select the working directory (it will tell you there is existing data--just accept)--Then (without scanning) you can go back to the export screen and do your post processing as normal (or you can continue scanning if you did not complete).I am still learning about the software--But one big warning... If you have loose leaf binders to scan. Take the pages out of the binder and scan as single pages. If you try to scan "facing pages"--The software gets "confused" and does a very poor job of separating the left and right pages (the lack of solid binding seems to cause problems with loose leaf scanning). Just scan one page at a time works very well and is probably faster than trying to scan facing loose leaf pages.Unfortunately, Amazon does not let me post PDF+OCR, so I will post a few examples of scanned pages (glossy, single page B&W, and B&W two facing pages single scan).
