Great device

Works great. I use it on my friends to ensure sober driving.

Its perfect

Very nice saved me ass the other night When i got pulled over

Accurate and repeatable

This breathalyzer seemed to be very accurate. It was repeatable to the same reading when alternating between people using it. I would say it is one of the best bangs for your buck in breathalyzers.

Fairly Accurate Breathalyzer

I’ve had the product for a little more over than a week now and I can say it’s fairly accurate. At first, the readings were way off but that it’s because it was being used consistently without letting the machine rest and not changing the mouthpieces. When you use the product, you must make sure you have not drank or smoked within the last 10 minutes and use a new mouthpiece for the most accurate reading. If you follow the steps above the breathalyzer will work appropriately. Also, the mouthpieces can be washed and used again so buying new mouthpieces is not required.

Worked well. Was able to convince some friends to UBER home instead of driving home.

I got this because I thought it would be funny to bring to a party and let people guess each other's BAC levels. The package came with the Breathalyzer, 3 AAA batteries, an instruction manual, and 4 tips. Each tip came packaged in their own plastic bag. After putting the batteries in and reading the instructions, it's ready for use. The breathalyzer is very sensitive by the way. According to the instructions, it recommends that you don't drink any alcoholic beverage 10 minutes before using the machine. It also recommends that you wash your mouth out with water beforehand. Press and hold the power button for about 2 seconds to turn the device on. From there, it'll prompt you wait as the machine warms up, and then blow into the device with the tip attached. The device will read out your BAC level in 3 different ways. If your BAC level is high enough, the backlight will turn from blue to red. It was fun to use and try to guess everyone's BAC level. While using it, I was able to get a few people to reconsider driving home after the party and use an UBER instead. I thought this was a cool device. It's a shame that it only came with 4 tips though. I'm sure that you can find some replacement tips on Amazon.

Great product and price

This is a great little breathalyzer. I used to have one that I paid over $100 for, and it stopped working after a few uses. This one is accurate and have had no issues for it. Great product and great price!

Works

It worked amazing for my needs

Glad I purchased

Good product for the money.

Wow!

Works great! I've used it at parties to show people just how long it takes for several drinks to metabolize out of your system
