Review: El producto está perfecto, es una lástima que el que me mandaron trae un fallo en la pantalla, deben de poner más verificaciones de calidad o mejor protección a los producto para que no sufran estos daños. =(, me han hecho la devolución y lo pedí de nuevo me a llegado uno nuevo sellado y sin problema, gracias desertcart 😍
Review: The unit is smaller than I thought looking at the pic. Than does not take away from the gauges. They have worked great. I have no complaints. They hook up to the temp probes and vacuum gauge with out any problem. I have had them on many all day jobs on some large systems and the battery indicator still says full.

## Questions & Answers

**Q: How can this unit provide an evacuation function but the unit does not accurately measure microns and requires a separate micron gauge?**
A: You need a separate micron gauge

**Q: Is the warranty valid outside the US?**
A: I don't know I would think so you would have to ship it back to were you bought it .

**Q: Do the games measure microns? or is the separate probe a must?**
A: It will measure microns internally though the hoses. The probs only measure line temps. I have the wireless versions and the kit comes with the micron sensor

**Q: do this kit has hoses?**
A: No. Hoses are separate.
