Customers Reviews:

This product has received over 4,700 reviews on Amazon, with an average rating of 4.6 stars out of 5. Customers praise the accuracy of this breathalyzer, and some have compared it to police-issued breathalyzers they used on the job. Customers also compare the BACtrack S80 to the BAC table, which calculates your level of intoxication based on your weight and number of drinks consumed.

According to the instructions, this breathalyzer provides accurate readings if you test 15 minutes after your last drink. Some customers have complained that the product only lasts about 200 reads and that they must contact the company and pay a recalibration fee. However, this frequently did not work, leaving customers without a working product and out of the money they paid for the recalibration.

What Is It Useful For?

It's difficult to put a price on knowing you're under the legal limit for a DUI charge. With a long list of federal approvals and a straightforward format, it's difficult to argue that the BACtrack S80 isn't worth the money.

Customers Reviews:

This product received an average Amazon rating of 4.4 stars from over 3,200 customers, with many praising the breathalyzer's small size. Customers also appreciate the ability to connect the BACtrack C6 to their smartphones. The app has some interesting features, such as telling you how long it will take until your BAC is 0.00 percent and letting you order an Uber. However, some customers claim that the reading was too low for how much they drank, and others claim that when they blew into the breathalyzer, an error message appeared.

What Is It Useful For?

The BACtrack C6 can be worn as a keychain or slipped into a bag or pocket. However, if you are too inebriated to drive, you should call an Uber. This breathalyzer simply speeds up the process.

The Rofeer not only displays your reading but also flashes green, yellow, or red and beeps one, two, or three times to indicate whether you are sober, still safe to drive, or not safe to drive.

Several buyers claim to have received a Rofeer that appeared to have been previously used. Others claim that the Rofeer's readings aren't always accurate because they've been completely sober and received a false positive.

What Is It Useful For?

The Rofeer would be an excellent, low-cost gift for a newly-turned 21-year-old who is still learning their alcohol limits. This is possibly the best breathalyzer to keep on hand at a party because it comes with multiple mouthpieces that can be used by different people.

The BACtrack trace professional breathalyzer is designed to detect even the smallest amounts of alcohol. Unlike most breathalyzers, this one measures three decimal points.

1.87 x 0.63 x 4.25-inch, black body

Slot for two AAA batteries

Platinum fuel cell alcohol sensor

Saves your last 10 readings

One-year warranty

Customers Reviews:

This product has received over 1,000 reviews on Amazon, with an average rating of 4.5 stars. Customers report that the BACtrack trace reads your BAC level more accurately than breathalyzers that only read two decimal points.

Several BACtrack trace reviews advise switching out the mouthpiece or rinsing it out between uses to improve accuracy because alcohol can accumulate in the straw, causing the reading to rise with each use. Some customers complain that the BACtrack trace detects a reading after they've used mouthwash, but this is most likely due to the reader being more detailed.

What Is It Useful For?

This product is designed for users who value accuracy above all else, making it one of the best breathalyzers available. Its recall data can help you track your overall BAC level after only one or two drinks.

BACtrack C8 Breathalyzer looks and functions similarly to the C6 model, but it is slightly larger. Because of the C8's size, you can use it instead of the mobile app to calculate how long it will take you to become sober.

You can still connect the C8 to your phone via Bluetooth if you want to see your BAC readings on a larger screen and access other features like ordering an Uber.

Key Features:

2.50 x 0.66 x 2.20-inch, white body

Built-in mouthpiece

Slot for one AAA battery

Platinum fuel cell alcohol sensor

Optional Bluetooth connectivity to smartphone

Estimation of when your BAC will be 0.00%

One-year warranty

Customers Reviews:

After just over 1,500 Amazon customer reviews, this product has received an average rating of 4.5 stars. Several customers have stated that they have been using BACtrack for a long time. Some people have owned the C6 version before, but prefer the C8 because it is a little larger and allows you to use the reader rather than the app to calculate how long it will take you to be sober.

According to some customers, the C8's results are less accurate than those of other BACtrack breathalyzers, making it unsuitable for drivers with a history of DUIs. These same drivers want to check their blood alcohol content (BAC) level before blowing into the breathalyzers built into their vehicles.

What Is It Useful For?

If you're looking for connectivity and functionality, BACtrack's step up from the keychain is a wise choice and may be the best breathalyzer for you. Having direct access to Uber is a big plus, and we like being able to see more on the device than the smartphone app.
