Bests & Worsts Reviews from Amazon

I'm guessing the four and five star reviewers largely have collections of old negatives and slides, aren't picky about them and consider this a handy device for scanning them quickly into their computer. From that standpoint, I suppose this is adequate. That said, don't pay any attention to the "20MP" figure -- the focus on the scanning surface is nowhere near that accurate and if the sensor was 5MP, you wouldn't have any lower quality from the scans. The color reproduction (as some commenters have said) is pretty bad also. You can use various tweaks and auto-adjust tools on your computer to make the pictures look "good", but you can't get them to look "right". The exposure is very non-linear, there's a lot of hot-spotting in the scans, etc. The non-linear exposure is the worse part -- you can't get any detail in the dark part of the scan without completely blowing out the lights. The device allows some adjustment via its screen, but the color reproduction in its screen isn't accurate enough to adjust anything anyway. If you're a fan of Instagram, you'll like the results from this. Even very sharp, bold-colored slides shot on Fuji Velvia will come out nicely "Instagrammed", with a nice vignette, washed out colors and the other aspects people seem to like in their cell phone pictures. However, not really what you want if your shots actually had reasonable quality to begin with. I was able to get a single good quality scan from a slide by basically scanning it like an "HDR" photo -- scanning a -2, 0, and +2 exposure, aligning them in the computer and merging them like an HDR photo, I could get a "reasonable" scan... in about 15 minutes of work. Considering a "professional" quality slide scan would cost maybe a buck a scan, that's not even remotely worth the time. My ten year old Epson scanner with a slide attachment does a far superior job, even if its only a 2MP scan. So... basically, big skip on this unless you just have a stack of carousels of 70's era slides that don't have any resolution or color accuracy to begin with.
