The Good
Considerable reduction in time and expense when having to dispense the same sample multiple times.
The Bad
Volume selection and choice of dispenser tips is quite confusing to start with.
The Bottom Line
Good for saving time when dispensing the same sample multiple times (e.g. cell washing for antibody staining) but quite hard to understand how the number of pipetting steps correlates to the volume selection dial and the tip volume. I would recommend investing in an electronic repeater pipette instead.
