This product came totally inaccurate. The 5.0 ml setting pipes out 7 ml liquid. The 4.0 ml setting pipes out 5 ml of liquid. There is a setting to calibrate, however buyer beware if you do not already possess a calibrated instrument to fix this one.

I purchased both the 1-10ml and 100-1000ul pipettes. The 1-10ml has worked great although it needed calibrated. The 100-1000ul has never been accurate and won't calibrate. The calibration nut screws all the way out, so I can never calibrate it. To dispense 1000ul I have to set the pipette to 700 and measure accuracy ever time I use it. I've torn it apart, cleaned it, lubricated it with the same result. I tried contacting Four E's several times and never got a response. I will be looking for another vendor.

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 Amazon return window literally closed two days ago.

This functions exactly as you expect and is extremely accurate. I love how easy it makes measuring liquids. This is my first time with this brand and see no reason to choose anyone else in the future!

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.

[original review] Want to add the random factor to your work? If so, the Four @ "High-Accurate" variable pippetor is the pippetor for you. Each draw will vary by a factor of 3x or 4x from the next in the series. Life is too full of certainties, thrill in the excitement of never knowing what will come next![edit, eight months later] They just refunded my purchase price, so I increased the rating.

Initially I was so in love with this product. I use it quite often, but it broke irreparably after just three months of use. Thankfully, the producer refunded the full price and the situation was resolved.
