Ease of use was good. I was not happy with the calibration report. it did not have any data. I would expect a calibration report to show the percent error before and after calibration
Very educational to see how a relatively small amount of alcohol can impact bac. Good to know how much alcohol I can safely consume! Worth many times the price to,avoid a DUI.
Pairs with your phone quickly. Fantastic for making sure that you are drinking smartly. My favorite aspect is the "time" function which lets you know when you will be sober. It's amazing how long it actually takes to process alcohol. It's great to be able to better know your body and how it reacts to drinking under different circumstances. You can "guess your BAC level" so that you can use the device to better familiarize yourself with how you feel at different levels of BAC, keeping you informed and making better decisions. I've had friends use it at the bar and decide not to get that "one last drink" after seeing where their level was and while this hasn't happened yet, I can see it being useful to convince people not to drive when they feel okay, but are actually at a higher level of inebriation than they thought. I recommend this product to anyone who drinks and look forward to using it more.
