Review: UPDATED REVIEW (2024-04-05): After posting my critical review (below) the company immediately reached out to me and offered to refund my purchase or send a replacement. I was frustrated with my original items defects, but considering the companies rapid polite & professional response I decided it was appropriate to give the product a second chance, it is possible after all that the original device I received was purely a defective unit, an anomaly. They sent me a replacement that arrived within a few days and that replacement has been performing properly since I received it. I am upgrading my review to 5 stars. I of course understand that occasionally products may be shipped with a defect. When considering products to buy online, more important than any rare defect, is a companies demonstrated history of good customer service. This company resolved my issue rapidly which makes me comfortable purchasing from them in the future. As such I now recommend this pipette. My replacement is working as it should and the price is very reasonable. Previous review below (2024-03-20) Very disappointed. Pipette lasted 30 days. After 31 days it is now inaccurate by OVER 20%. This is basically a toy that falls apart rapidly. This pipette should not be used for any purpose that requires even semi-accurate measurements. The only purpose I can see for this is to give it to your kids so they can pretend to do science experiments. Or maybe for something like mixing food coloring for coloring Easter eggs. I was using it to measure liquid extracts for adding to recipes, but even for that purpose I feel it is unsuited. I tested it when I got it and it accurately dispensed 5ml. NOW when I choose the 5ml setting it dispenses 6ml. When I select 4ml it dispenses 4.8ml. That is 20% EXTRA. An eye dropper style squeeze pipette is more accurate because at least it has volume measuring lines on the tube. The frustrating part is my desertcart return window literally closed two days ago.
Review: In my original review I said this item was not accurate not realizing that the plunger was two stage. Actually it is very accurate. To draw fluid only press the plunger to the first stop then to the second to dispense. You don't use the second stop to draw up fluid.
