    Works pretty accurately, it’s a good tool To use just to make sure you’re not over a limit and think you can still drive. Prove you wrong for your safety and others!

    Works pretty well and is pretty intuitive. It on your tales a few seconds and you have the result. I haven’t used the app capability yet but looking forward to it. I love how small and portable it is.

    Haven't used it much but the few times I did I was glad to have it. When on se it's a great buy but even when not, it's still cheaper than a DUI!

    Its a good product for the value. If you're looking to make sure you’re not too trashed to drive it works well. It seems pretty accurate if you do some calculations.
