Enjoying So Far
I’ve been using this for a few months now and I would say that it has worked for me for the most part. Sometimes it gives an error if you don’t blow into it just right, which can be frustrating when you’re intoxicated lol but makes sense. When I blew .141 and it said seriously impaired, it was true. I definitely couldn’t walk straight or talk without slurring. So to me it would be close to accurate. It may not be exact, but at least I know I have something telling me I’m over the legal limit. The main reason for my lack of a 5th star is the app. So you see the screenshot I took. When I go back and look now, it reads .145. Not much of a difference I know, but that number shouldn’t change.
Thank you for your feedback
