Before getting this one, I had two return ones made by two other brands because they didn't work. This one has worked every time I've used it, and as far as I can tell, it's totally accurate. It has some nice extra features like the bluetooth connectivity and phone app, and the memory on the device. But the most important thing is that it works, it's compact, and it looks and feels sturdy and well-built. It does not come with any kind of case, so if you're going to carry it around in your pocket, I'd advise getting a small bag for it.

There is no point to this product. I’ve tried it several times over several days. The readings are so inconsistent in a given timeframe (both absurdly high and low) that no confidence in the readings can be established.

The C8 is very accurate when used as instructions recommend. Battery (AAA) last long time. Works with your cellphone if you like but not necessary. Tells you time when you're alcohol will be 0.00 . Simple and easy to use. Get one, gives you piece of mind knowing you are not going to be drunk driving.

Only wished it had a internal log, vs having to use app for that feature.

Accurate breathalyzer, the bluetooth feature is kind of cool, but a bit unnecessary as the device display works just fine. Not really worth spending $100 on but if you can find it for under $50 it's a great buy!

It’s very easy to use. I like that there is an app feature, but you don’t have to use the app to use it. Tells you everything right on the screen such as BAC and how long until sober.

Great product. I am very familiar with Fuel Cell technology for BAC testing. This works as advertised. Follow the instructions!!! I can not understate that enough if you want reliable results. All you have to do is "wait" 15 minutes after you ate, drank or smoked before testing and this will work perfectly. Nicely priced for this level of accuracy.

This was second one I bought. And unreliable so had to return back. They both from different sources were faulty products. Constant malfunction was the common trait in both. And hence my conclusion of bad untested unreliable design.

Awesome! Works as expected. Might be a little sensitive since it is a fuel cell sensor.

I love that it also tells you how long until your safe again :))))))
