Great product. Everyone who drinks should have one. The risk of hurting someone or getting arrested isn't worth it. For accuracy, you must follow the simple instructions.

Very accurate. Works great, but I wish it were a bit more intuitive when trying to turn it off.

Seems to work as advertised and seems to be pretty consistent… Seems to work as advertised and seems to be pretty consistent, but only a friendly police officer could prove its accuracy, which is still to be determined.

…to make sure you blow into it for about 5 seconds until you hear the double beep…works well, but you need to make sure you blow into it for about 5 seconds until you hear the double beep.

Works as advertised. Works well. I tested it all day and it delivered consistent results. Easy to use. Smaller than an average smartphone. Recommended.

Very reliable and accurate! I bought it in 2017 and it has met all my expectations. It's been used almost a thousand times and is still very accurate. The batteries last a very long time. It does its job with peace of mind!

Great product. Good quality. I would recommend it. Great product. Works great. Easy to use. I'm not sure how to compare it to others, but it gives me peace of mind whether I can drive or not.

Everyone needs one, wish it were free… Okay, before I had one, I wasn't sure if I was allowed to drive or not. After getting into trouble, I decided to take responsibility. I work as a bartender to earn extra money. This device makes me feel good. Don't waste your money on keychain breathalyzers. This one works perfectly.

Durable and well-made. Works well. Seems to be accurate and durable. I haven't had any errors or battery issues. I've had it for almost a year.
