Question : Digital Alcohol Breath Tester ?
Anyone try these things ? They are CHEAP on ebay.

Are they reasonably accurate ?

Talking about the higher end ones that give you a score between 0.00 to 0.19.

(Cheaper ones just use green for 0.00, yellow for 0.02 and red for 0.005.
Thanks. The cheapies just arent any good.

The good ones are $ 100-200.

Not really worth it for gags.
