AlcoSense NF Breathalyzer for France (Twin Pack)
- Product Review (submitted on 8 November 2014):
- Bought this as a test/experiment to see if I'm over the limit the next morning after a night of drinking. Both times I have tried it the crystals just turned a darker yellow no sign of green which indicates no alcohol or 'wet test' but it doesn't say what 'wet test' is. Does this mean they are faulty tubes? I'd be very surprised if I'm under the limit considering how much I drank last night.
