Purchased this breathalyzer for safety after a few close calls. The LED screen is bright and clear, making readings a breeze even at night. Its user-friendly design ensures I can test quickly before getting behind the wheel. Results are almost instantaneous and spot on – a must-have for responsible drinkers.

I like this alcohol tester. It's very cheap, but it's really useful. It allows us to know our physical condition in a timely manner when drinking at home. I really don't like excessive drinking

Needed a compact tester for travel. The LED display is crisp, and operation couldn't be simpler. Prompt, exact outcomes have boosted my confidence on the road.

I am very opposed to drunk driving, but sometimes after drinking, I am not sure what is suitable for driving. This device is very convenient, and I can always keep it in the car now

At first, I just bought it to test with friends for fun when going out to play. In fact, it is really useful in life. If you are someone who loves drinking, you can buy one and try it out. Not only can you avoid being fined for drunk driving, but sometimes you will also remind yourself to drink less

My child has reached a rebellious age and often plays with friends until late at night. I bought this device to test whether he drinks alcohol at night and how much he drinks. Fortunately, now he knows that with this device, he has become much more restrained, and even if he drinks, he won't drink too much

Sometimes after drinking alcohol, I become very excited. My wife will take out this alcohol tester for me to measure and tell me that I have really drunk too much. Perhaps I don't believe what she says, but in front of the data, I still believe haha, so I will be much quieter
