“I bought this one after owning the keychain for 8 months. This one is way more accurate, more than .02 times accurate than the keychain. Worth the money. On the keychain you will blow .02 times higher than the pro.”
“I bought this about 6 weeks ago, and have used it once. It worked great and will provide me with the resource that I needed to perform on the spot testing when the need arises.”
“I work at a local PD and tested the PBT (Backtrack) on the same machine (Datamaster) we test individuals on for OVI's that is court approved. It was a little low but not by much. The reading should have been .100 but the PBT read a .098. That is actually better than the PBT's we use in the field. For $85 and a 1 year warranty, you can't beat this product. Plus my friends and I have fun with it when I'm not at work. I wish the case held more mouth pieces but that is the only down fall.”
“I bought a new S80 that seemed good. My very old S70 was recalibrated, but gave bad results. You gave me a good deal on trading in my S70 for an Element; now I have complete faith in both the S80 and the Element.”
“I bought this product a few month ago and have been happy with it. I don't have any real ways to measure how accurate it is scientifically but when I've been drinking and use it, it seems to be accurate with how I feel.”
