The tester does it's job as advertised. The tester is not very useful unless you have the standard radiator cap and radiator or you have the adapters needed. The adapters can be expensive. A complete set of adapters will cost more than the tester, $300 or more. Check the STANT web site for the adapter you need and make sure you are willing to buy the adapters you will need before you purchase the tester.

One of the lowest priced cooling system pressure testers available, yet very well made of good substantial materials. The pump body is all metal - no cheap plastic. Most of what you are paying for in the more expensive kits is all the adapters. If you can use a standard "A" cap, then a simple model like this that doesn't come with a lot of adapters is all you need. It works very well and is very easy to use. You can also order from Stant any adapters you need. Stant is a very well known name in cooling system components, and the quality of this tool shows why.

I have owned the Snap-On version of this item in the past and there is no point in paying over twice as much when this item does the same job. I just used this a few weeks ago and it found the leak in 15 seconds. It's a fairly straightforward item and it does what it is supposed to do. Again I see no reason to pay over $100 for a Snap-On/Matco/Mac brand when this one does the job just great. It's well-made and works perfectly.

Works just like the expensive ones on the tool trucks Mac, Snap On or Matco. It has been flawless. I work in the truck industry

Device works well. Must buy adapters to make work for specific applications (Honda civic). Adapters are overpriced but they are needed and fit well.

This unit worked exactly as intended. It enabled me to diagnose a problem with reasonable certainty before I took a car in for repair.

Good price on unit and it arrived in reasonable time. Works well, but I did have to buy a separate adapter for one vehicle (Nissan).
