“I just bought the product today. Some friends told me it works well. After using it twice it will no longer work, it says fl. I guess that means it's not getting enough air or a good enough flow. No matter how hard or soft or steady I blow it still says fl.”
“We have random drug and alcohol testing where I work and if someone smells alcohol on you, you can be tested. I was concerned that I could have a BAC from a previous night of drinking so I bought this unit at the recommendation of a friend. Was happy to learn 5 to 6 hours would have me blowing 0s after going to bed with a 0.13. This little device is well worth the 30.00. When you consider the cost of a DUI, it would be cheaper to call for a helicopter to take you home.”
“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.”
