Review on Calibrated Medication Eye Dropper for Accurate Measurements by Tom Goodlow
terrible quality - no suction, almost impossible to draw anything down the tube
These are the worst drippers I have ever used. When squeezing and releasing a pear in a bottle filled with water (!), the pipette draws in no more than a quarter of the volume of the tube. I don't know if downspouts work with incandescent bulbs, but they're completely ineffective. I've never seen a dropper bulb draw less than half a tube volume. A complete waste of money.
- Easy to use
- Poor instructions
