Until now, I was using alcohol checker of the same manufacturer, but the sensor part became non-responsive and it replaced it. The judgment lamp is not displayed finer than before, and it turns out that automatic judgment turns off automatically in 30 minutes
I feel inconvenience.

As a disadvantage point, there are times when it is an error that you have to forcefully blow your breath on the sensor part, so it is regrettable that no exact numerical value comes out! It is! As a point of merit, I think that it is good to have a battery replacement unnecessary because it is a 100 V power supply type. It is lightweight, compact, very simple, easy to use and easy to use by anyone.
