Am very pleased with the BACtrack S35. It was inexpensive, extremely easy to use and very helpful after an evening of drinking. Am in a position that if I were to get a DUI, my job would be over. Nice to know exactly what your Blood alcohol level is.....and the directions were correct. It is very important to wait 15-20 after your last drink to see what your level is. Highly recommend it!

After installing the batteries and turning on the device. My first test registered .50?(the only drink I had was milk,water, and some mouthwash which I did not swallow. My next test after drinking 3 beers .000 ? I do not think I need to count on this devise to get any indication of how much my bac would be at any time .I just wasted a little money

Fairly nice product. Not cheaply made. Works well and I trust the results. On negatives I don't know how other ones work but the 25 second count down till you blow goes fast and might goof up someone. Also the numbers are a little hard to see in the car at night. I am 62 years old so maybe I'm getting slow and blind but I am not having problems even when I blow a .10. I have gotten all kinds of reads from 0 up and they seem quite accurate. I feel iy was a good deal at $50.

We have used the product several times and found it to be easy to use, of good quality, and it seems to correlate with alcoholic beverage consumption. We cannot speak to it's calibration with NIST standards for Blood Alcohol Content measurement and therefore if the number it provides is accurate.

I blew three tines and got three different readings. I followed all instructions. It did however indicate that I was not yet ready to drive.
