Great machine. Must be very close to the leak, you can't just point it at the fridge to see if there is a leak in the fridge. But you can visually inspect potential leaks and see if there's anything to worry about. It worked great in tests and the test material provided made it possible. I like how easy it is to use the device. I also like the very sturdy case it comes in. You want to know that your tools stay safe in the field. This one will! I also like that it runs on regular batteries - it's a lot easier to keep it going. It's comfortable, if not too ergonomic, to use. The readings are clear, the only small problem is the gooseneck between the sensor and the device. It's not always easy to carefully put it back in the suitcase. This is the only negative I can say about the device and it's not bad enough to cost it one of its 5 stars. Great, easy to use and reliable tool.
