it's quite small so easy to carry around. Warm up time is only 10 seconds. clock and thermometer are nice little extras. And you can't complain about the price.
the air intake and release is not carefully guided so you get a lot of condensation on the LCD-screen after blowing into it. Even on the batteries drops of water starts to build up after a few blows. Also it looks like you are blowing more air around then really into the sensor. (maybe i can fix that with a bit of silicone?)
First unit i got was defective but dealextreme quickly replaced it. Very impressed by their service. First impression is that the sensor is not accurate at all. For example people blowing 0.0 while they are clearly drunk. But couldn't really test the unit enough to elaborate on that.
Nice little toy to have fun with,but i wouldn't use it for "drive safety" as stated on the box because common sense will be more accurate then this unit I think.
