Prestone AF-1420-6PK Antifreeze/Coolant Tester, (Pack of 6)

True to form

This thing is so handy and inexpensive to purchase everybody should have one. Not only for mechanics, everyone should have one of this unless you never touch under the hood of your car. Makes it simple to check the concentration of coolant once you have mixed your own or done a coolant change and are replacing your coolant. Super easy to use and is cheap made but has lasted so far with multiple uses. Its easy to read and tell the concentration of the coolant mix in your system.

Works great, and for a good price relative to others. Takes just a little practice to get it full by squeezing the bulb--no big deal. Highly recommend.

Great for testing your antifreeze, if you live in a cold climate..

Makes testing antifreeze easy.

Compared it to my (very) older one like this one and they both agreed with each other. Cheap money for a good product that could last a Very long time with proper care. Just follow the simple instructions indicated on the tool.

The item was not delivered to a front desk or had it signed by a person, it was delivered to my front door and i happened to see it when i looked outside. No email with a picture and time it was delivered like before, what's going on ??

Works fine and good quality.
