I bought these to try and speed up the digitizing process for LOTS of slides. Once you download these bins, which are the most tedious part of digitizing aside from sorting and aligning the slides, they really speed up the process. I have 6 of these bowls. They are much faster than the standard cut sheet tray that Wolverine includes in his scanners. We recently scanned a collection of slides using a team approach with one person sorting and uploading and two others scanning. We were ready for a 3 pack cookie workout but were done after a pack and a half. One caveat: when these trays snap, they actually snap. It takes a little practice to open them again easily, but this is quickly mastered. I recommend it if you're scanning more than a few slides at a time.
