AlcoSense NF Breathalyzer for France (Twin Pack)
- Product Review (submitted on 12 January 2014):
- I liked the French authority approval.The main reason for not liking the product was that as i am slightly colour blind / colour defective, I can't tell the difference between the yellow and the green. there just isn't enough colour variation from its dry state to the activated colour. Rendering it useless to me. There needs to be a much greater colour difference between the dry crystals and the activated crystals.
