Decided to give this a try. I've worked in biochemistry labs frequently, so I wanted to see if a super cheap aliexpress pipet would be in any way similar to the real deal. It's a functional pipet, and it actually feels like a legit one (has an ejector button etc). There clearly is a large standard deviation as far as accuracy goes tho, much broader than is true for expensive pipettes. But considering the price, im not mad at it.
4 stars, and that’s generous, because the bag with the disposable nozzles was dirty - from the inside! The price is good, but the nozzles arrived with dirt particles on them...
