Instructions

Device fits in a pocket or on a keychain.

Requires frequent recharging or replacements due to limited capacity.

Simple and convenient to use without hassle.

I keep this on my keychain and use it any time someone is drinking and preparing to drive. It's also handy to confidently identify how many drinks it takes to get any one person to the legal limit. I don't use the replacement mouth pieces- I just wash it after each use!

perfect!

bactrack.com

Cost & usefulness: BACTrack was the top-rated in an independent test in Road & Track, among much more expensive competitors. Simple and easy to carry/use. Great device if only used for a CONTROLLED test at home - so one knows what each meter-level of intoxication "feels" like (observing mood, function, coordination, focus, etc.) - for future reference when out. It's also a perfect, end-of-night-out conversation piece that initiates thoughts about driving responsibilities and risks (without the meaningless cliche remarks like "are you sure you okay to drive?") Now you all know how drunk each of you are . . . so, what will you do?

Useful accuracy at a reasonable cost

Bought this product because of article in 'Car and Driver', April, 2014. It outperformed the other four units, even the Backtrack $150. unit. I've blown into it on two or there occasions and it gave fairly consistent reading based on how much I'd had to drink and how long after I'd taken the sample. For the price you won't beat it.

Most accurate for under a couple of hundred

I bought my entire family these small breathalyzers for Christmas stocking gifts. That was two years ago! We have made it a habit to use it before driving. Valuable tool to see what/how much is your limit. We recently had to replace one of them, but overall I really believe this is a must-have item. It's small so easy to carry in purse, pocket or car.

A Must Have

My mom passed these out to my sisters and me at a family gathering earlier this year and we thought it was funny but it has honestly been the best gift ever! I use it all the time when I am out and if it says I am close to or over the legal limit then I call a cab and don't worry about if I *think* I am ok to drive and hope I don't get pulled over. Such a thoughtful and useful gift for someone you love. I just got one for my husband as well as the additional mouthpieces because our friends ALWAYS want to use it to to test themselves before they get in the car. I absolutely love this and highly recommend!

Best Gift Ever!

This is a great product. I purchased this after I was pulled over after an evening with my family. I had had a couple of drinks over a 5 hour period of time. A state trooper pulled me over and I was given a sobriety test and a breathalyzer. I passed all of but the way the trooper made me feel and the possibility it could have been in a life changing situation made me order one of these as a reminder for all of my adult children and myself to think twice and this can provide a moment of focused thought to help guide a decision. Way to easy to think a couple drinks are ok, all depends on the time that passes, not so much how you think or feel and the damage will linger forever.

I would buy from backtrack again

feels like $7

Not gonna lie, I have an ignition interlock.  I was looking for something accurate to use before I start my pick up early in the morning to go to work.  I didn't want to spend alot of money as I usually don't drink on work nights anyway.  Just messing around with it, I can tell it must be more of a novelty than anything.  I haven't had a single beer in 3 days and just blew .03.  I know what things can trigger a false reading too, none of that applies here.  It just flat out isn't accurate.

not accurate.

Bought this because I was going to my neighbor's house for dinner, who is also a state trooper. I'm in the wine industry and was curious and thought this would come in handy during wine tastings. 2 glasses of wine over a very long dinner, plus an hour after for socialization I tested 3 times. .35, .30 and .30. Shocked I used my neighbor's state issued breathalyzer twice. .09, and .10. 15 minutes later and after swishing around some water in my mouth I used this device again. It was even higher....-.39. I just opened the package yesterday. I'm not diabetic nor on a low carb diet. It's so wildly inaccurate it's not even worth using as a party favor. Apparently I should be near death right now, according to this thing.

Worthless even as a party favor

I just got this to keep around for myself or my buddies. I brought it home and used it sober and got a .00 as expected. I then drank one beer then waited the 20 minutes and tried it again. I got a .17, I thought maby it was a bug but tried it again and again and got a .23 plus. I weigh 280 lbs and am 6'2"...but apparently I'm trashed off of one 8oz beer. I dont think so. Even my wife tried it (who had nothing to drink) and even she is blowing a .08.

Not accurate
