I got these to use in my big bottles of Fragrance oils. They work perfectly. Grat suction, it measures perfect too. They reach to the very bottom of the tall bottles when they are almost empty which is what I needed these for. The glass is a nice thick sturdy glass. The bulbs seem to be made from a good rubber material s I think they will last awhile. My only concern was they arrived in a shipping bag that contained a thin box with all the components in it. This box was crushed upon arrival. I was afraid the glass parts would be broke but they were wrapped in a bubble wrap which I guess saved them or I was just lucky. Otherwise, the product itself is really great quality.

The product seems well made. The tops bulbs are old stiff plastic. I thought I was going to shatter the glass putting the bulbs on. They held up despite some serious force. I may try heating bulbs in hot water to soften them next time, this may help or ruin them depending on the type of plastic. Once assembled they work fine. The bulbs will likely crack with more, time, UV, or heat but it will probably be fine for some essential oil extraction, few experiments, and some garden poison measuring. The poison one only stays with poison.

I'm very pleased with how strong the glass is on this set. I've been pretty rough when using the mining rod and the droppers have has a few close calls from falls without any of them breaking. I'm very pleased with my purchase.
