I tried another $30 range unit that had 100s of more positive reviews and it did not work at all... False readings when I had nothing to drink for days!! I was skeptical about getting another low price unit since the one for $120 had many positive reviews but I'm not a heavy drinker and could not spend $120 just to know how much a glass or 2 of wine affects me... So I gave this one a try.
My first test... Blow in it a few times while sober and sure enough it registered 0.00%. Then I took it to my jobs Xmas party where normally I drink wine like water since it's freeeeeee! The instructions state to always take 3 tests and use the average for your final level. After 2 glasses my nose and cheeks started getting numb, but I'm still aware of everything... I waited a bit and the first reading was 0.05. The 2 other readings were 0.04x (where the X varied). To me these numbers made sense. I was buzzed and not drunk. I drank 1 more glass throughout the dinner and in the car I took 1 last test (picture). I tried 3x and each time got the same reading of 0.04%. I drank the first 2 glasses before the meal, the 3rd glass I didn't like the wine therefore did not chug it but drank it slowly with my meal taking small sips. I felt the buzz dying down as it got closer to leaving time, therefore 0.04 seems correct to me.
I feel that this breathalyzer is giving me the correct reading of m actual BAC level and gave piece of mind of driving home. If I were at 0.08 (nj legal limit), I would have not driven home. Either taken a ride with someone or waited it out.
Every drunk should own one of these and be more responsible as when they should drive, or 1 friend on a group should own one of these to prevent their friends from getting into accidents or hurting others.

I like it a lot but...
I bought this item on a whim that with as little or as much as myself or the girlfriend drank, that I was curious where my tipping point was, this satisfies that curiosity.1. Quality - 4/5 - This thing is plastic, made in China but seems quite durable, I think there are some improvements but overall very good2. Price - 5/5 - I think this is well priced for what it does. Quality breathalyzers cost quite a bit more and this is that sweet spot, not too cheap, but not expensive either.3. Value - 5/5 - The value of this is in my opinion is worth it to have around, do I need it? No, did I want it for that niche curiosity, you bet!4. Cons - given what I've stated above there are a few complaints that I have, but these aren't deal breakers. First, it comes with no batteries..really? Second, the battery compartment is undeniably hard to get off, I question my strength sometimes, but come on! Third, the mouthpieces, although plenty is provided, they aren't snug when inserted, it'll get the job done, but I think they could have made them attach a little more secure, again not a deal breaker, but a want in a revised version, please!5. Ease of use - 5/5 - Instructions are fairly clear on what to do, there are picture type screenshots of the screen and what you'll see before you start using it. You press power 2 seconds, wait 15 seconds and blow! Easy! 3 colors represent your alcohol levels, Green, yellow, and Red, nice!6. Overall 5/5 - Quality and cons aside, this device does what it says in a no-fuss box, with ample mouthpieces to get you testing fairly quickly. And of course Amazon, amazing!

Everyone should own one of these. Worked great.
