Customer Reviews

Not sure just yet....
There are instructions and a full description at the sale site and complete directions inside the keychain itself. I didn't realize and am disappointed that each device can be used only one time. If you order (one) you actually get (three) breathalyzers...but all are disposable.

1. Get the key from your friend or family member 2. Alcohol impairs judgment never test yourself 3. Test him with the LegalLimit Breathscan.If color changes to blue/green cast, this person should not drive 4. Keep the key and find a designated driver or call a taxi. 5. Save a friend or family members life!

THESE THINGS EXPIRE!!!
I still give it 5 stars because they work if used properly.

Step one: Follow directions for product.
Step two: If you find yourself breaking the glass tube and blowing into the tube, DON'T DRIVE

That's your que that you need to call a cab.

has anyone else noticed..
this product does not mention once how it works or how to use it. It simply tells you that it is a disposable personal alcohol detector.

Thats it.

Therefore, if you plan to check your level more than 4 times, go ahead and buy a normal breathalyzer, it will cost you less, and you will know what you're getting when you buy it.
