“The BACtrack C8 is remarkably close to professional devices. It makes it easy to know when you're under or over the legal number, or perhaps you want to be well under. It works great, easy to use, fast and reliable so far. I've only had it a couple of months, though, so it could go out of wack. I've purchased 2 of this exact model but from other suppliers, and they didn't work at all.”
