Science projects!
Style: High-range
These are perfect for science projects - being able to complete multiple tests at once helps a lot. We did start off with all in one bowl to see that they all worked and said the same thing. Would buy again if I ever needed to…but I think we’re set.

Great to be used for experiments, but need to be put away because of ease of separation.
Style: High-range
Great size and ability of use for early learners, but need to be put away as the ability for the pieces to separate with improper handling with little ones will occur.

POOR QUALITY - JUST TOYS
Style: High-range
I thought I got a good deal with these cheap thermometers. I manage a building so I wanted to try out these cheap units at different locations in the building to monitor the HVAC systems. All I wanted was to get relative temperature readings at different locations so I figured accuracy within a few degrees Fahrenheit should not be a big deal. However, when they arrived, the glass tubes will not even stay put so I have to put Gorilla glue on each one once I have positioned them correctly and all the same. They are not easy to read even if you take time to position them properly on the plastic holder. Then I checked the temperature readings while having them all side by side and they vary by as much as four degrees Fahrenheit. I have placed the bulbs at exactly same position as the others. I have wasted more time than I am willing to give to these units. Now I have to place them at locations where four degrees difference is not a big deal. I'll have to use a more reliable thermometer as standard by which these units are calibrated against. Now I'm certain that these units are only GOOD AS TOYS so Amazon should re-classify these under that correct category. ... show more

8/10 read accurate
Style: High-range
Review Image by Condi
These are okay thermometers for the classroom. I'm a science teacher, so need to have enough thermometers for my students to do experiments with. Pros: -sturdy plastic -easy to read -fairly inexpensive easy for kids to use Cons: -only 8/10 read accurately when calibrated - most were within 5 degrees F when I compared them with a digital thermometer, the other 2 were at least 15 degrees off on both cold (ice water) and hot (nearly boiling water) temperatures -because they're not exact it makes it difficult to conduct accurate scientific experiments in class ... show more

Good value but needs adjustment
Style: High-range
Great value for the entire pack. Glass tube is a little loose and slides about an 1/8 inch. This effects accuracy. I added a little folded paper shim under the bulb and now it reads correct. Working for weeks now, epecially in the heat wave. I use them indoors at our desks at work.

Comes in a pack of a gazillion, but the kids haven't broken any yet! I'll be selling extra thermometers at the homeschool book sale for years and years. Hooray for science!
