Won’t connect to my phone.

I ordered this and waited for the shipment to arrive and when it finally did it did not work at all. It would turn on and connect to my phone and when I would blow into it as instructed it would send me a notification that it didn't accept my breath test and try again. I tried probably 30 times. I powered the breathalyzer down and back on again multiple times and tried breathing harder and softer and every time I got the notification that the breath was not excepted into try again. What a waste of time.

Absolute trash! I came back to re-review, and found my first review completely deleted. Obviously reviews here are a manipulative scam.

Straight up doesn't work. Going to return it.

The device it self it an off reading but the app woth it seems to be 99% accurate

This app is absolutely useless. Pay $100 for the higher end model that works with the app only for it to error out as low battery even when fully charged. Better off buying the cheaper one that digitally reads than one that needs the app

It works as advertised! It’s on my keychain all the time. The App is fine. Instructions not there, but anyone should be able to figure out how to connect and use, with a bit of intuition. Start using at home. Results will surprise you! This is as useful as a current driver or walking license! Obligatory it should be. Take care. V

I have the bactrack c8 And it does not even try to pair to the app

Doesn’t grant a username, email doesn’t register despite it literally emailing me, and on top of which is very clunky to use. As for actual usage, I don’t know because it won’t let me use it.

I cannot get my keychain back track to pair with the app on my iPhone. I guess I’ll have to send it back. Very disappointed.
