For the price and for all that it does, I have to say it is overall a good product, but there are caveats. I previously had a 15 year old high-end Nikon Cool Scan II, which needed some repair but is out of service. So for my limited budget, I determined this was the best product; in addition to scanning negatives and slides, it also scans photos of which I now have many. My main purpose, though, is to scan old pre-digital negatives from the 80's and 90's. And I have come to the conclusion this flat-bed scanner is best for photos and that for my purpose a dedicated negative scanner would have been better. You scan negatives from a template which holds the negative strip on the flatbed which then scans using a focused beam to produce a very high resolution image. However, I found all of my scans so far produced have a glare through white space, which I was unable to correct via scanning or software manipulation. It could be the negatives, but I believe it has to do with the quality of the scan tech. It is also slow in the scan routine. I think this flat bed design is best for photos. FYI: During installation I was prompted to download a 'patch' for my Mac 10.12.2, which addresses a year-old negative review concerning compatibility.
