Now, we all know that there is nothing like visiting the local bar for a few drinks with your colleagues after work, but in an age where the watch word is to drink responsibly, you can never be to careful.

And with this fantastic little gadget you can get an instant indicator as to whether you are safe to drive home or whether you should be taking a cab.

Simply hold the power button down to activate the LED and when it turns green you gently blow onto the grill located in the top. Wait a couple of seconds and if the light remains green then you are under the 0.05% BAC, and good to drive. If the yellow LED lights up then you are bordering on the 0.08% BAC and probably should be checking your bus time table. If the yellow and red LED’s both light up then its definitely time to hop in a cab.

Oh, and just in case you cant quite find your way to the nearest bus stop or taxi rank, then this clever little device also comes with a handy built in torch.

Measures 11 x 8 x 2.5 cm

Thank you for delievering the gifts I ordered on time ( inspite of the bad weather). They all arrived in good condition and the presentation of the gifts were great so I was told by my family.
