Exactly what I needed for a preschool activity.

Our two and three year old daughters absolutely love these test tubes. We do water activities with them outside at their picnic table. Keeps them entertained for a very long time!

My 4 year old grandson was ecstatic to play with these. Very durable. Well made. Will last for many years.

I chose these because the cylinders had both front and back scales, which should make it easier to make accurate measurements. Unfortunately, the front and back scales do not line up! In the 10, 50, and 100 ml cylinders, they differ by about 0.4 mm; but in the 25 ml cylinder, they differ by a whopping 2.4 mm! I calculated the volumes based on inside diameter and height of the scale marking. The molded scale agreed with my calculations to within about 3%, but at the lower end, some of the printed scales were off by as much as 25%. This product is fine if you ignore the printed scales and don't need better accuracy than 3%.The very next day after sending feedback to Moveland, I got a the following response: "Thank you for letting us know that the graduated cylinders set issues. I have reported this issue to our quality controller. Can you take a picture of the cylinder scale for us? This will help us better improve our products." And they offered to send me their $14.99 set of graduated glass cylinder at no charge. I sent them scanned images and the measurements I took on their plastic cylinders, and they responded the next day stating that they had tested the product, found the same errors, and have taken steps to correct the problem.Their glass cylinders arrived today, and they do not have the problem I found with their plastic ones. If you want plastic graduated cylinders, I believe the set I originally ordered would be suitable for applications not requiring extremely high precision, but only after their manufacturing problem has been corrected.

Well I got these first my daughter that has tooken an interest in chemistry. When I got the package and opened it up everything was in order except one of the beakers plastic base was broken. Everything else was fine. I was a little bummed about the broken one but other than that.... I'm good.UPDATE:So they contacted me and offered to resolve the problem. They responded like SUPER fast! I am very satisfied with the results. I understand that things get broken from time to time during the shipment process but for them to reach out so fast to resolve this problem.... and was so polite, I am changing my rating.

My 8 year old daughter loves them, requested a set that wasn't "kidish" safe plastic with a real look to them.

Good for adult learners

Good in size and assortment, but I was expecting the plastic to be more transparent. It is milky, and whitish
