already worth the price paid for the device, as it helped my boyfriend not get behind the wheel after going out with some friends one night. the product does go through batteries quickly though. still worth it! i would say i doubt i will get it calibrated, because its about as much to buy another new one as it is to pay for calibration.
Good once broke in. I used one for a year and a half with no issues bought a new one and failed that night on a .023 that it did not read. Add 3 months to my blow and go in my truck. Other than that swear by it!
I bought this product yesterday. I had a party last night and consumed quite a few drinks. Towards the end of the night I wanted to see how it worked. It never blew over 05. There is no way I would have got in my car after that many drinks. I'm glad I was at home and didn't have to put my trust in the keychain breathalyzer. Maybe I just have a faulty one.
I bought two of these keychain breathalyzers because I thought they were neat. The only time they will show an actual reading is right after you have taken a drink of something. I can drink 10 beers and still show a .00 on both of the devices. Not worth my money, but a good conversation starter at the least. I definitely would not buy one of these if you are planning on relying on it before you drive home.
I purchased this so I can test b4 driving but I'm having issues with the battery life. I only get 5 to 7 tests on brand name batteries, because of this I can't count on this units results when the battery is low. Can you help?
