The glass graduated cylinder is better, but the exudation of the additives in the safety ring is bad. The white powder becomes very dirty about the cylinder when trying to put on. Even when washing or wiping, the white powder from the rubber ring has not disappeared, so we are not using the ring. I chose this product because there is a safety ring, which is terrible.
If it is not a glass product it corrodes with pesticides. I have used it outdoors, but since it is glass it has broken. I think that it will not be like the previous one because rubber for protection is attached. I think that it would be good if there was a storage case.
