Breathalyzer, Portable Keychain Breath Alcohol Tester for Driver, Highly-Accurate Result Digital Battery Power with 5 Mini Mouthpieces

Very accurate and it saves lives. Wish I had one years ago. I take it to restaurants and bars too.

Works. It it’s not very accurate. You get the quality that you pay for

I CANNOT BELIEVE THEY ARE EVEN ALLOWED TO SELL THIS PRODUCT!!!! It simply does not work AT ALL. I go from having a 0.0 BAC, to ONE beer later sky-rocketing up to .19 (more than double the legal limit) with the screen flashing "Danger". This device is a complete piece of garbage, and has not once given anything close to an accurate reading. The seller of this product is also very shady, because the device received 4/5 stars, but when I clicked on the reviews all of them were written about a completely different product (some kind of wash cloth). It's true what they say : "You get what you pay for".P.S. I only gave it one star because Amazon required it in order to publish this post, in reality I would give it a negative 5.

This is the second breathalyzer I purchased but not nearly as good. This one takes forever to load up and reads in accurate results often and you run out of breath by the time it’s done. The other one I bought was another one off of Amazon. It was orange but I don’t remember the brand. Worked great

works great, easy to keep with you.

Does the job

Unfortunately, this is garbage. Different readings within seconds of each other. Readings all over the board. Returned after 2 weeks, but didn't ship it in time, so lost $18, and have to landfill this. :(

While this a cool gag gift it’s not reliable. After drinking a beer and waiting 15-20 min we tried it and it read a BAC of .23 which is not accurate.
