I too used pipettes for a while. They are very slow to use, *^&%
frustrating to read in low light, and take a lot of time to clean. I
THOUGHT I was getting more consistent / repeatable prints for all this
effort. When I discovered I really wasn't, I dropped the pipettes and
returned to droppers. Happily, quickly, and with no regrets. For what 99%
of us do, pipettes are way too much precision. Lots of work, no gain.

Do you clean between uses?
