This is a pretty neat way to get fine control over chemical solutions for use in perfumes or anything where you need to deal with tiny amounts of chemicals. Be sure to read how to use them online if this is your first time using one, as their method of operation is not immediately obvious. It came with a printed quality control test sheet that showed the error percentage from testing for mine, which is about 1.5%. I used it for injecting controlled amounts of perfumes and aromatic chemicals for candle making in order to get repeatable results. The gears and mechanism all seem to turn nicely, and if treated with care it should last a long time. The little loop on the handle is very comfortable and did a lot to make it more controllable as well, which is really nice when you are doing work with chemicals that you do not want to spill or misplace.

Works well, easy to use. Light weight.

This is a nice cost-efficient pipette, great for my garage lab setup. The pipette seems accurate with the testing I put it through, compared to my brand-name models for the same size (P2.5), so largely not very good below 0.2-0.5uL, but that's to be expected. It works well for both regular and filter pipette tips. The lock mechanism is very helpful since the dial adjustment is quite fluid and easy to change accidentally if unlocked. I also like that the pipette comes with the tools needed to troubleshoot or repair the piston, as well as colored caps to keep track of the pipettes in a matching set. Overall, the pipette works well for my lab use!
