“I bought a go keychain. Out of the package, it never turned on. I used the battery it came with and also my on purchased batteries. Nothing managed to turn it on.”
“I had my unit about a month and my friends and I have a good time testing each other. really good to know that most of us blew a 0.2 to 0.4 the next morning! on our way to work! we all were surprised. the only issues I had is that it is hard to hear the tone and after several tests in about a week the count down timer started to stop and restart again. but it had no effect on unit. I think the battery was getting low. I wont give up the unit.”
“Nifty device to help you protect the lives of your loved ones and everyone else on the road. Purchased this as a gift for my husband to use after a night out. Has been great so far. Seems to be accurate. We get the same readings between tests. Correlates well with physical symptoms of intoxication. Item did scratch fairly easily in our pockets with keys, but at this price point I'm very satisfied with this product.”
“I've used this device for only a week, but so far I'm pleased. It easily fits in a pocket and works reliably. It uses a single AAA battery, so replacement batteries will not break the bank.”
“I use this almost every time I go out and it's fun (and educational) to see the results. I've always wanted one to help me gauge my limit and this is an extremely afforadable way to do it! I will likely be purchasing several of these for family and friends as stocking stuffers for Christmas!”
