A breathalyzer or breathalyser (a portmanteau of breath and analyzer/analyser) is a device for estimating blood alcohol content (BAC) from a breath sample. The breathalyzer is one of the most affordable breathalyzers available. It can be used in a wide variety of settings including clinical test applications and for personal use. Its uses advanced semiconductor alcohol sensing technology to quickly take a breath sample and provide a blood alcohol content (BAC) estimate. The lcd graphic display will indicate how inebriated you are, whether it be dangerous (over 0.05% bac), unsafe (approx. 0.02% bac) or safe (under 0.02% bac). Displays “caution” when result is within 0.02% – 0.05%, displays “danger” when result equals to or higher than 0.05%.

It just so happened that a family member got nabbed for DUI 2 weeks before this product came up, so we had to give it a try. I would dearly love to check the accuracy with a police-grade unit, but I don't have the connections to do that. This unit is easy to use and will hopefully prevent somebody else from making his mistake, and him from making another. He has already lost his license and will probably lose it again, along with other sanctions. This is MOST highly recommended!

Compact, sleek, light-weight and easy to carry around. The LCD screen is bright enough with large, easy to read numbers. Operation is super simple with just a press of a button. Takes one 9V battery and the whole thing comes in a nice little carrying case. And price is about right for the quality, design, and ease of operation. This is def a life-saver and highly recommended to have on hand at any gatherings or parties where alcohol is abundant. I recommend to buy.

The breathalyzer works great. It is accurate and even if it’s sensitive, it helps to keep us and our friends safe. It comes with two mouth pieces and funnels. All can be sanitized, which is especially important during these times. This is great for parties, when you are having so much fun, you don’t pay attention to how much your drinking. It comes with a battery and it fits in my large handbag.

A person really can't be too careful about this sort of thing these days. This is a nice little device to keep in the console of your vehicle, or at your home bar. I tried it several times to gauge its accuracy as much as possible from home and it seems about right. The device tells you to wait 15 minutes after your last drink to test it. I would caution that your blood alcohol level peaks at about 45 minutes as the alcohol continues to absorb into your system. What's nice is that this device lets you know when you are at .03 which is the cut off for wet and reckless as they say.

Simple and straightforward breathalyzer. Press the Power button, wait for the breathalyzer to calibrate(it gives a countdown) then blow into the mouthpiece as soon as it says blow. You MUST take a deep breath, then blow continuously without stopping till the device makes a beep. It needs a steady stream of your breath or else you will get an error. The steady stream is not hard to maintain, I have always been able to do it properly, drunk or not. At a party I tested its accuracy and I felt good about the results it gave. It comes with a nice carry case that keep it all in one spot. Perfect for leaving in your car for when you need it.

In all honesty every single person who imbibes alcohol should have a breathalyzer. The human body is not the best at letting its user know how drunk he or she is or isnt. To get a real idea of how intoxicated you are you're going to need to take a breathalyzer. Putting things in perspective in the moment is incredibly useful, even if you are yourself intoxicated. However this units biggest positive is its use in parties. Having a party and a guest who has been drinking is ready to drive themselves home? Take the breathalyzer first. In the moment people will claim they are ok to drive and even insist that you give them your keys. However once they take the breathalyzer and realize they are in fact not ok to drive they become much easier to deal with and rationalize with the situation. Hey you may have just saved someones life.....Saving a life is certainly worth the cost of one of these.

So to test it, I used it after a long charity event party. I was not driving. It was a long event and I had drinks over the entire time. When I got home I used the device. It put me over the limit which I knew I had to be. The warning beep went off and it showed me at 0.092 the limit in my state is 0.08 I really like this unit.

I had wanted one of these since my buddy got one. I really had no idea how many drinks correlated to being over the legal limit for what length of time. Is it ok to have one beer at dinner, or stick to none at all? I didn't want to be anywhere close to the limit. I know not drinking is the best and that is what we should all do. This unit seems very well made and comes in a very nice case. It was very easy to use. It does have a beep and a click like another reviewer said. The beep isn't very loud. The display tells you everything you need to know though.

This Secureguard BAC Portable Breathalyzer, in my opinion, is a piece of equipment that should be essential to anyone who does social drinking of alcoholic beverages and is considering driving anywhere. Case in point: I tested this product on a friend who stopped by our house and had a few drinks with us. He didn’t act intoxicated and he told us he didn’t feel intoxicated but just a little relaxed. He wasn’t slurring his words at the time I used this breathalyzer on him and yet, as you can see from the photo, he blew a blood alcohol level of .299 which is way over the legal limit! Needless to say, we had our friend spend the night and depart in the morning. Had he left that night he could have gotten a DUI or worse, killed someone due to his less than obvious impairment. This Secureguard BAC Portable Breathalyzer is so easy to use. After the nine-volt battery is put in, you just press on the power icon for three seconds and it turns on. Immediately, it starts counting down to zero and when it reaches zero, it says “Blo.” At this exact point, you or the person to be tested blows into the included mouthpiece with a full breath. If the one being tested is legally impaired, this breathalyzer turns red and says “Warn” above the BAC number. This device is both easily portable and easy to use. If it has any issue it is that the case can be tricky to open. I recommend removing the device from its case before doing any drinking so that there won’t be a struggle to open it later. Seller recommend.

Arrived in good time. We got it in 3 days after placing our order. It has a solid build; really good quality and accuracy. Also, it is extremely easy to use. After having a few drinks with my friends, we tried the breathalyzerc and the results for both of us were pretty much identical. My result read .031, and my friend would read .033. That gave me the confidence that the Bac tester is accurate. Thankfully, the product comes with 5 breathalyzer mouthpieces. It’s easy for personal use or for group testing. Both can be cleaned and recycled. Perfect for testing multiple friends or family members.

I purchased this for my husband and myself. We have both tried it on several occasions where we have had alcohol and it seems to be very sensitive and accurate. I had one drink and tested an hour later And it reflected accurately. My husband had several and it appropriately noticed us “red” and a higher level. Would recommend as a precautionary tool to use.

I have had this breathalyzer for about 2 weeks now and have been able to test it out multiple times with various people and it is very easy to use. I have yet to blow above a 0.016 which matched someone half my size who drank the same amount so it is tough to trust the accuracy but regardless it is fun, easy to use, and helpful to better understand how BAC affects you.

I’ve always wanted a breathalyzer to have a better idea of how alcohol affects my BAC and how different levels of intoxication feel compared to the BAC. I bike or ride share when heading out to drink, but it’s nice to be able to know what my BAC is after having a couple of beers.

This little guy is awesome! We had a party this weekend, and I told everyone they can come, but if they drink they’re not driving. I have plenty of sleeping arrangements. The breathalyzer was perfect because I hold onto everyone’s keys when they get to my place, and they’re only leaving if they blow much below a .08. Work perfect for my intentions, but I have to admit we had a lot more fun seeing what everyone was blowing Even If they didn’t plan on leaving! Also very handy they give you multiple tips so everyone can use their own without having to sanitizing just 1 tip.

Great product. It has many mouthpieces so you can share and take the breath of your partner and friends if we are going out drinking and then driving. The device is accurate. I drank 1 beer and waited 20 minutes it said I had .00 bac. After 2 drinks and waiting 20 minutes I registered a .02 so I do believe this breathalyzer is accurate it has a bright LED so you can see the reading at night. The warm up time is also very good, other ones I’ve used would take 2 minutes to warm up. Highly recommended

I do not know how accurate this breathalyzer is but I tested it on my husband and I to see the difference in results. My husband had a few beers and his came back 0.05 and my first blow came back 0.01 and I had no alcohol to drink so I tried again and it came back 0.00 as expected.

While I certainly don't have bloodwork to compare this to for accuracy, based on my preliminary testing, it is providing the readings I would expect so I'm happy so far. Both my partner and I have tested this without consuming any alcohol, and both got the anticipated 0.00 reading, and after a drink or two. For example, about half an hour after drinking a small glass of wine, I got 0.027 (which is about what I'd expect).

I purchased this product to replace one I'd received as a gift that I've apparently lost in the ensuing years. It's useful to have a breathalyzer at home when you have company over just to forestall any guests' arguments of "But I feel fine to drive!" While we don't have many people over these days due to the pandemic, my parents do stop by after I've gotten a negative COVID-19 test and frequently have a glass of wine or a beer with dinner. Lately they've been expressing feeling the effects of even a single drink, so I decided it's time to invest in a new breathalyzer to see if they've just become lightweights during quarantine or if they're actually becoming impaired from one drink. Better safe than sorry!

I just got this today and don't have any alcohol so can't tell for sure how accurate it is but I did try it out and it did show 0.00 when I blew in it without drinking. It is easy to use. All you have to do is push the power button for 3 seconds then a 20 second timer starts once the time hits 0 you blow into it. It will beep while you are blowing you stop blowing after it stops bleeping. Very easy to use. Can't wait to try it after drinking

Without having a professional breathalyzer to compare the results with, it's hard to say how accurate this breathalyzer is. But judging from our experience as well as some of the 16 other reviews, it seems pretty accurate. At least it should get you in the ballpark. It's certainly more accurate then some of the breathalyzers that cost less than $50. It comes with 5 different mouthpieces. You could put a sticker on one of them to distinguish one from the other in case you are going to be testing yourself and others regularly. Overall, I'm pretty satisfied with the quality and accuracy.
