The unit has a very clear display and has auto shutoff feature .
My favorite features:
Clear instructions. Audible feedback. You can really hear the fuel cell heating up then click on when primed. Hepatic feedback is always nice
I was excited to find out the packaging included a velvet style cinch bag to store the unit and mouth pieces. It was a nice touch from Easy@Home.
Accuracy seems fairly true. In my test I blew thru twice and got the same result. Tests were back to back.
Message from the manufacturer the unit will need to be recalibrated every 500 used or roughly every 6 months. The user manual didn't offer any details as to the recalobration process. Only offered an email address to contact them.
Haha My old units i just had the sober people blow thru for calibration. Looks like things have gone a long way !
