AlcoSense Stealth

Excellent device

I have had mine just over 7 years now. I get it regularly calibrated and it has always been very close to accurate.
It is showing some signs of cosmetic wear and tear but still going strong.

trustworthy results

I have had one of these for approximately 4 years now, and so have a couple of my friends. It has been tested side by side against a police issue very expensive model, and has always been accurate. The best money we have all spent!

Received & tested

The response & delivery time was very prompt & efficient.
The unit itself is easy to use & observations at the time of consumption of alcohol appear to be relative as an indication but unable to determine how accurate it is. Do you have any guidelines that you use for calculations or can you provide a chart that would be indicative of readings ie: as in number of beverages that are consumed in a time frame etc. & how long it takes for alchohol to be out of the system ?

AlcoSense Stealth

So far so good, excellent product

Stay safe and stress feee!

I'm not what anyone would call a heavy drinker. After being 100% conviced I was under the limit and using a friends Alco Sense Stealth, I had to have one.
I was right on the limit .05 - and very shocked!

I drive to work and am a responsible person so AlcoSense is an essential little gadget. I have peace of mind when I go out now. Highly recommended.
