“I've found it easy to use. I've compared its results with one of the larger, more expensive models. It has varied a little bit, and I tend to believe the larger model was probably the more accurate.

“I've had this for about a month now. I use it to pre-test prior to blowing in my breathalyzer in my car. Since purchasing this I have not had any violations!! It has been very accurate.”
“I bought this a lil while ago, if I go out to a bar it goes with me. I make sure I am legal to drive or call a cab. A few times I thought I was fine to drive I didn't feel to buzzed and I blew a .11 yep cab time no dui for me. Thanks Folks!!”

I had the simpler version (that doesn't tie into my smartphone) and it worked great.”
