“Miss product was amazing I would use backtrack again. It had to be it actually tells you how much you drink and when you should wait, which is amazing. Maybe there will be less DUIs.”
“The product is not very accurate even when following the steps stated on the box the sensor works but is not accurate. Can drink a bunch of water and blow zeros when you are not at zero.”
“We've had this product for about a month now and I would buy it again - it seems to work very well. It's easy to use, compact, and gets the job done. We have had one reading that appeared to be false because it was different than another 2 readings at the same time, but it wasn't off by much. Overall, impressed with the product.”
“If you love to have drinks w friends, this is a must have for partying responsibly! Makes for the very best gift as well! Do not hesitate to purchase!”
