    I absolutely love my BACtrack keychain, It's smaller than expected, really easy to use and very fast. It seems incredibly accurate as well. Highly recommend.

    This is the best thing ever. It's so small I carry it in my front pocket and don't even know it's there. It's nice to be able to read my BAC on my iPhone or right from the display. My friends and I love sitting out by the pool with wine and testing ourselves. Before testing with the breathalyzer it asks you to guess your BAC. We always guess too low! This isn't a nice to have, it's a must have!

    I am so happy with my Bactrack, I almost never go out to the bar without it. Fast, accurate, fits perfectly in my pocket. It's actually a lot of fun, too. Glad I bought one!

    this device seems to be very accurate. i have checked it's readout when i have had nothing to drink and it reads all 0's. i have also checked it after drinking 2 regular light beers. form what i have read 1 beer is around .015%. after drinking 2 and testing 15-30 later this device had readout of .03. seems very accurate.

    2nd BACtrack and enjoy the improvements

    This is my second BACtrack and both have been great. I love that the C6 has both a standalone and bluetooth option. It's great that it still connects to my BACtrack app for details. The standalone option is great if you're just out with friends and having a good time and want to easily keep track of your BAC.

    Doesn't work

    First, the product was delayed a few times after I ordered it. I ordered it on 1/8 and received a few emails about returns and delays, but not one of the actual delivery date to track when it arrived. Second, I obviously then had wait until I was going to drink to use it and when I did, I found that it does not work AT ALL. I took several readings over a weekend and the numbers were all over the place. It went from a .02 to a .8 and then back to a .02 and then to a 2.2 within a small time frame ... and similar results were given the next night. Third, when I came here to return the item, the site says that it needed to be returned by 2/4 (I for sure didn't even get the itemed delivered until at least 1/12, so what is that date based on?)....and now I am out $74 and there is nothing I can do about it.
