Alcohol Tester Breathalyzer Keychain (0.19% BAC Max)

Pros: the device works and shows some results. it will sniff alcohol in your breath after 1/2 bottle of beer in half an hour after drinking. it never shows any alcohol when you didn't realy take it.

Cons: the weak side of the device is it's accuracy actualy. if you try to take another test within 10-15 minutes after previous one, the shown results would be zero or definitely incorrect. don't know why it happenes but you should wait atleast 20 minutes after taking a test before taking another one to get some kind of reliable results.

Other: you should get used to this device to get reliable results. anyway it is quite sensitive to alcohol, so even after only 1/2 of bottle of beer it reveals the fact of drinking.

Pros: The device is very cheap and there is absolutely nothing to complain about for this price! You can take off the mouth piece to clean it, 5 mouth pieces are included. It is very easy to use.

Cons: The housing looks a bit cheap, but hey...it IS cheap!

Other: Just a cool gadget, get it!

Pros: - Funny little gadget - Comes with several mouth pieces - Very easy to use - Mouth pieces can be cleaned - Funny to use when drinking with some friends

Cons: - It's definetly not accurate. I've tested this thing several time. One moment it says I blow 1.5... then I drink some more.. test it again after half an hour.. and suddenly I have 0.5, and after that 1.1.. etc. But still... It's funny to play with.

Other: Funny gadget, but not more then that.

Pros: It seems to work, it always give 0.0 when you didn't drink at all, but if may give some false negatives, too...

Cons: as said in the title, you can't rely on this to anything else than playing with your friends, it can give extremelly different reads for testings, even if you wait like 20 minutes....

Other: It;s worth buying it just for playing, or to check if you already absorbed all the alcohol you've injested, but can't relly rely on the results :)

Pros: Good built quality. Good price, although not excellent. Comes with many mouthpieces. Nice display with numbers reading (and not just 3 LEDs with levels reading).

Cons: Not very precise; keep in mind to use it as a reference only, or for playing around. Many times it keeps reading zero just after reading seomthing else. It seems that has been broken, but if you try again some time after that, it returns to work.

Other: Good toy/reference for the price. Nice display information. Sometimes seems not to work.

Pros: English: Its a cool Breathalyser, its small, you can put it into your pocket and you can use it as a keychain, the price is also great for a breathalyser, great to use on partys or in a tequilla day!
Portugues: è uma ótima bugiganga, é pequena e voce consegue colocar ela no bolso, o preço é bom e voce pode usar como chaveiro, é ótimo pra brincar com os amigos ou para ver como está antes de sair ao volante

Cons: English:
it doesnt mark the correct alcohol level, but it is a great gadget anyway
Portugues:
nao marca o nivel correto de alcool, nao é confiavel, mas mesmo assim é uma ótima bugiganga

Other: great gadget
ótimo produto

Pros: fun great product. what a blast to have at parties. it was fun to see where i was at after two beers then after two more and seeing what that compares to my friends.the size of a person definatley affects how alcohol is absorbed. this was a lot of fun at a low price.

Cons: it started to not work the more people used it. i attribute this to everybody's spit getting the sensor wet. because the next day it worked again just fine. other than that its great. i wish it went past .19 but probably better for my liver that it doesnt.

Other: get this and have a blast. its fun for everyone.

Pros: You can try to point this thing to a road police inspector and say "I'm not drunk, I've tested myself, I do this every time". But that's all. Wait, that's not all, it has five different mouthpieces, if you're still worried about hygiene when drinking.

Cons: There's only one con: it doesn't work. When you didn't drink anything, it shows 0.0. So I tried on one of my friends, who drank a glass of wine. Device shows 0.19, and I didn't believe she was able to get 0.19 from just one glass (100g or so). Then I tried to test it on myself. After one beer I've got 0.19.

Other: Can show if you drank some alcohol or not, but nothing more. I don't understand why bother with LCD and stuff it it can be just one green and one red LED for the same functionality.

Pros: It’s quite good for this price. The build quality is good, the plastic don’t look cheap. Display is fairly readable, and informative. I mean that you don’t have to read the manual to figure out how to use the device. It comes with extra mouthpieces, which is good, because more people can use it with their own mouthpiece.

Cons: The battery cover is inconvenient to open, it’s too tight. And it cracked on the first time I’ve tried to open it. Batteries on this device run out very quickly, from fully charged, to almost empty it took about 15-20 tests. Then it started to show false results, showing 0.00 when there’s actually 0.40. Too bad you can’t see when the battery is week. But I think that it is a problem of all cheap breathalyzers.

Other: In overall it’s a good gadget, to have. It may even be handy, if only I knew whether it’s telling the truth. But for now it’s just a toy for me.

Pros: Come? without battries, without cd without backlight.Withoutbox.According to quality no complaints.
Shows result in promille.when 0.3 shows warning. When 1.9 shows a danger.
It’s quite good for this price. The build quality is good, the plastic don’t look cheap

Cons: No backlight,Cd and battaries as shown in topic
The battery cover is inconvenient to open, it’s too tight

Other: The tester is no bad.The quality is on the level,and it can be a keychain!
