terrible quality- zero suction, almost totally incapable of drawing anything into tube
These are the worst droppers I've ever used, anywhere. When squeezing then releasing bulb in a bottle full of water (!!!), the dropper totally fails to draw in more than a quarter of the tube by volume. I don't know if the dropper tubes are the wrong ones for the bulbs, but they are completely ineffective. I've never seen a dropper bulb that drew less than half of the tube by volume. Total waste of money.
