Vision ScientificVS- TP20H Variable Volume Micropipette 2-20µL x 0.02µL | True One-Handed Operation | 4-Position Volume Display | Volume-Change Protection

This product was not designed by Vision scientific. The manufacturer is Walter products incorporated and the label is not displayed on any of the images on the advert.The tip ejection key doesn't work.Dissatisfied.

The micropipette i received is a brand called "Walter" not Vision Scientific.The volume setting wheel doesn't work after calibration.It looks good though. one star only for the design because nothing else works now. It's hard to return the item in these circumstances so I just lost my money.

2 out of 3 pipettors failed calibration after 1 year of barely using them. DO NOT BUY THIS BRAND!
