Customer Ratings & Reviews

I ordered the BACtrack S35 online. The product overview said it gives accurate results. When i received it the package said estimates BAC. This is not what i wanted i don't want an estimate. I want accurate results.

It works really good so far. Reads pretty accurate after many drinks helps me not to drive and it’s pretty slick. I can put it in my pocket and check my BAC before driving. I get an ubet if it’s over 0.05 BAC

It is affordable, but I cannot really tell if the measurements are accurate or if it is even really working. My fiance had 2 glasses of red wine and 30 minutes later I used the BACtrack breathalyzer to test her blood alcohol content and it read 0.01 both times. On another occasion I had 3 well drinks and tested myself about 45 min later and it only showed 0.02. So I am not sure if this device is accurate at all. Maybe I got a bad device, or I need to use better batteries. I just wouldn't recommend it from my short experience so far.

Every time I play with this and have not had anything to drink - it always displays 0.00 If I have drinks it registers a number. I have not tested then compared with police findings and don't really want to attempt that test :-)

works as advertised I used it a few times first time reading was.05 and a few hrs later and after a few drinks reading was 0.6 both times I waited at least 20 min before testing

Bactrack is a life saver, more people should own one.
