  4. Stanford Albert –

    I was looking for a way to test the vacuum lines a on my car that didn’t require me to bring my larger tester and this one actually surprised me on how easy it was to use. First it contains about every connector that you will need for a variety of hoses, all you do is plug one of the adapters into the hose, secure it, attach the flexible hose included to the adapter and the device, set the device and you get an immediate reading. I only tried it on the brake booster, but plan to get an attachment for my radiator next. I love that there is a flashlight on one end so they thought of the little details that you would need when working with the device. Overall it is high quality, very intuitive and something that I will use a lot on my vehicles.
