Title: Worthwhile product
Product review: This is a well designed quality product. The technical specifications are 100% accurate.The device has a long battery life. I have had several for more than three years and the batteries are still strong.I would guess that the battery life of this device is equivalent to the shelf life of the battery (unless, of course, it alarms frequently).These devices are very sensitive - the moisture from contact with a finger is enough to cause it to alarm ( that's a good thing - and a good way to test that it is working properly.)A very reliable and worthwhile device. I don't think you can go wrong purchasing one (or more). I sure didn't!
