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.

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!

bactrack.com

Saw the Car and Driver's breathalyzer review gave this unit their top rating and it therefore seemed like a no-brainer investment for the money. Works as promised and appears to be very accurate. It's invaluable for make sure you're under the legal limit before getting behind the wheel and really reminds you about how long it takes for alcohol to leave your bloodstream. Essential for leaving nothing to chance!

Great low-cost investment!

I am very impressed with this little backtrack. I purchased a competitor's product and it was not accurate at all. I feel very confident and trusting this little guy. Of course there is no substitute for using common sense. It is a certainly better than guessing.

Very handy little device

Have used the BACtrack several times. Tested with no alcohol consumption and various levels of consumption. The readings seem to be consistent and within reason based on the number of drinks. What I have no way to gauge is if the readings themselves are accurate compared to a police BAC test.

Small, convenient

Bought The BACTrack Keychain a few years back, and it's great! I've tried another of the Back Track Family in the same prioce range, and it didn't compare to this product. I've bought this for Family and Friends, and also recommended it many times. GREAT Item!

Great Item!

breathalyzer.ca

Tested alot esp at parties. Works great. Accuracy is spot on! Showed incline in alcohol as we drank and decrease as we stopped. Do not use right after taking a drink wait 10 mins so breath is not saturated. Directions say 20 mins but i saw no difference.

works perfectly!

walmart.com

Bought this unit 2 months ago worked good for 2 weeks then very inaccurate I have an ignition interlock and if I blow in unit and it says .01 I wait 1/2 hour it will say .00 I then know I have to wait 3 hours till I can start my truck.. not very reliable

not to impressed

feels like $7

I bought this product earlier today. Thought it was going to be a nice way to track my bac and also my friends if the "thought they were good to drive". But it doest work. Won't even turn on and I really don't want to drive back I to the city just to return it. Just awesome.

Didn't work right out of the box

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
