BACtrack BT-S75 Professional Breathalyzer: Accurately measure your blood alcohol content between the ranges of 0.000-0.400% with this breathalyzer. The 4-digit LCD display is simple to read and understand. Do not use this product as a tool to determine whether you should operate a motor vehicle or equipment. Always have a designated driver when alcohol is being consumed.
I've had this product for several months. According to the built in counter it has been used more than 80 times now. While more expensive than a lot of other devices, this one has been worth the money. It seems to test very accurately and consistently. I've taken it to a few parties where several people want to test themselves throughout the night. The relative results have always been as expected. We even throw in a few sober people in the middle and they always test 0.00. Many cheaper devices can test above 0.00 when no alcohol has been consumed. If you depend on the accuracy of the device, I wouldn't risk it on a lower quality product. Having removable mouth piece allows testing multiple people easily and they can be clean for reuse; although the more people drink the less they care about sharing. I also bought additional mount pieces for pretty low cost. The device does come with extras, but I figure drinking will lead to them being misplaced or being carried off by someone.
What's great about it: Accurate, Reliable
What's not so great: Knowing exactly how drunk you are
