This is the second Elitech product I have purchased, the first was returned immediately. The volume of the loudspeaker in the leak detector is so low that it can hardly be heard even in a quiet room. I wrote to support and asked if I could turn up the volume somehow. They did what I hate and answered a question with a question. Instead of answering me they asked for a video. I usually buy high end hardware but these days I have to replace a lot and I decided to try these brands and it didn't work, you can only return so much before Revain shuts you down so I saved this POS anyway and will replace it at Robinair in the near future and will make it a backup device.
