With the rising number of accidents that have come about as a result of drunk driving, going out for a drink or fun times with your friends continues to be a risk that may end up with some very dire consequences. To help you avoid such, it might be a good idea to get a breathalyzer, so that you\u2019re able to stay aware of your blood alcohol level, and know exactly when you\u2019ve had enough. The bactrack keychain breathalyzer should be able to help you do this, and retailing at only $29, it's certainly not expensive. We\u2019ve put together an insightful review to help you determine whether it's one of the Best Breathalyzers to go for, so go ahead and get to the end of it to see if it's the Best Personal Breathalyzer for you.\r\n\r\nWhy We Like It - Bactrack Keychain Breathalyzer\r\nAvailable in the color black, blue, red, green and purple, the Bactrack Keychain Breathalyzer is perfect for anyone who might want to have a small, easy to carry breathalyzer, and since it\u2019s manufactured in the united states, you can bet that it is of good build quality.\r\n\r\nPerformance\r\nThe Bactrack keychain breathalyzer relies on advanced microcheck sensor technology, where it\u2019s Semiconductor Oxide sensors use a tin-oxide substance so as to come up with accurate bac results. This is a bit different from the Fuel Cell Technology that\u2019s used by the Alcohawk Pro, but you can still rely on them both for on point readings. The bactrack keychain breathalyzer is also pretty easy to use, as it only has one button, and a red lit LCD display for easy visibility. It\u2019s fold-out mouthpiece ensures that no ambient air gets captured, so as to keep the results clean and accurate.\r\nSize\r\nAt a weight of about 57 grams, the bactrack keychain breathalyzer is really ultra portable, so you shouldn\u2019t have an excuse of not being able to carry it around. It\u2019s got a keychain that you\u2019ll easily be able to attach your keys to, and in doing so, you\u2019ll have a reason to carry it wherever you go. It\u2019s a lot smaller than the alcomate premium al7000, and will probably be a lot easier to move around.\r\nBattery\r\nTo keep it as small as it is, the Keychain breathalyzer bactrack was designed to only accommodate 1 AAA battery, so if you use it pretty often, you can expect to be changing the battery quite often. There\u2019s an aaa battery that\u2019s included when you first purchase the breathalyzer, so you\u2019ll be able to start using it immediately after you buy it.\r\nLife Span\r\nYou can expect to use the Bactrack breathalyzer for a pretty long time to get accurate bac results before the sensor needs recalibration. This is why it remains a very popular choice especially among users who tend to go out drinking a lot. Unlike the bactrack s80 breathalyzer, it doesn\u2019t really come with any mouthpieces, so you shouldn\u2019t expect to spend any additional money once you buy it.\r\nValue\r\nIn case your Bactrack keychain breathalyzer doesn\u2019t function as you\u2019d expect it to when new, you can always reach out to the manufacturer and get a replacement since it\u2019s backed by a one year warranty. The unit is also available in many different colors, giving you a wide variety of options to choose from.\r\nBactrack Keychain Breathalyzer Wrap Up\r\nIf you\u2019ve found this review helpful but still aren\u2019t decided on whether or not the Bactrack keychain is the right pick for you, we would recommend that you look into a couple of its customer reviews on Amazon, and maybe once you do so, you just might find it worth a try.
