Herain 20 Pack Glass Eye Dropper, 1ml Pipettes Dropper for Essential Oils, Skincare, Lab, Health Care, Measuring and Transferring a Variety of Liquids, Dropper

No complaints. They allow me to move small amounts of chemicals from one container to another, either one pipette at a time, or just one drop at a time. They work reasonably well as a backup means of doing drop-based measurements when the dropper tip on a dropper container fails. I don't know if the quantity of chemical being dispensed per drop from these pipettes matches the dropper tips on my bottles, but it seems to be close enough for my needs (pool water testing).

I have to give my daughter mct oil and these are great to get the oil out and less mess, the glass makes it durable and the marking of the measurement don't come off. Easy to use

I tested one of the 10.

I just received these pipettes last night. I immediately tried 2 of them out. They worked easily. I didn't get it really for the graduate measurements but I did notice that to get the 1ml it either is a bit under or a bit over. Like I said, that doesn't matter to me much since I'm using for DIYs and I use a scale to measure everything out. It was more for ease as a pose to pouring and getting spillage. They are sturdy glass, the suction is great. I like that it came in protective cases to fit 10 pipettes in each. I also like that they are reusable. I was using disposable one prior to. The value of the money is great for 20 pipettes. I haven't cleaned the 2 I used yet, I just soaked in soap and water. I will rinse later but I do wish it came with a brush or 2 to properly clean the inside of them. I will have to order some. Size is good but I will be getting a larger one for the projects that will need a larger amount of liquid. Versatile endless as you can use for medicine, beauty, drinks, and diy projects. I want to see how they work out after the cleaning since I had to remove the suction bulbs. I'm hoping once I put them back that they work as flawless as it came. If it does, I will be ordering more.

Great quality and just what I needed for liquid supplement

I am using these droppers to create custom colors of leather dyes by measuring precise amounts of factory colors.The glass droppers are easy to clean.

We use these to add drops of bleach to purify water and to clean stains. I like that these are glass and easy to clean and reuse.
