iPega 0.9" LCD Digital Alcohol Tester for iPhone / iPad / iPod - Black

Pros: Easy to use. Can tell you that you drank sometimes.

Cons: Never accurate. No matter how much (or less) I drank, it kept showing me that I have 0.5 g/l alcohol. I had 1/2 beers and tested, it was 0.5 g/l. After two beers, it was still 0.5 g/l. Moreover, you need to test it as soon as you drink. After 30 minutes or so, the product says you haven't ever drunk at all ! One thing more, it won't start when the screen is off.

Other: I wouldn't recommend buying this product.

Pros: It comes as handy, because of its efficiently small size. Due to it being small, it's also portable, you can easily carry it with yourself whenever you want. Works okay.

Cons: Maybe the price could be better, but it is still unbeatable. The package could come more protected, but none came damaged.

Other: Generally recommend that those who are looking for inexpensive iPega 0.9" LCD Digital Alcohol Tester for iPhone / iPad / iPod - Black.
