“I recently bought one of these because I did something foolish and now require an interlock in my car. I can usually have quite a big session that will carry over into the morning, so knowing that I'm at 0.00 is a requirement. So far this has proven to be extremely accurate. If you're a similar type of person this is 100% worth every cent. Far cheaper than the alternative, I assure you”
“Received the Baxtrack 2 days ago. Tested it earlier tonight at a bar, later at home. Before buying the s80, I read the lowest rating reviews. Fyi, I always read the lowest rated reviews first. Tonight, I had the chance to test the t80. I followed the instructions and waited 20 minutes after smoking, drinking, etc. The reading was dead accurate each time. After receiving the reading, I waited a few minutes and tried it afain. Each time, I received exactly the same BAC. After I got home, I tezted it again after having a few mixed drinks. My BAC in increased but stay consistent after 3 consecutive test 5 minutes apart. I expected + /- of 0.001 but each reading was exactly the same. NOTE: You can adjust the amount of time for each blow. Increasing the blowing time, increases the accuracy. Recommend increasing the blowing time for anyone who gets inconsistent results. I'm giving 4 stars rather than 5 because the s80 is NOT realistically portable unless you have a backpack or purse. You can't stash the s80 in your coat, jacket or pants pocket. This means that you need to either bring the conspicuous carry case into the bar. Yes, the s80 comes withb really nice case but you have to carry it like a purse because its too large for your pockets. So it's a highly accurate device but you'll look like a full blown alcoholic if you bring it into a bar then use it in public. If you care what strangers think, then it's better to test yourself in the privacy of a restroom or somewhere outside. That said, this device is well worth the price, regardless of calibration intervals, if you frequent bars and wish to avoid a DWI/DUI. I'm planning on buying the smaller keychain version for testing inside the bar, then using the s80 to later reaffirm the results. If you have any trepidation over the price of the s80, then reaearch the average cost of a DWI. Seriously, who cares if you need to recalibrate or replace it every 9-12 months. CONCLUSION: HIGHLY RECOMMEND! Drive safe.”
