Going out drinking? The BACtrack breathalyzer has got your back and will let you know if you're just too wasted. It'll also give you a detailed analysis of your condition. It connects to a smartphone app and calculates a fairly accurate estimate of how much alcohol is in your body.

Th readings are sent to your iPhone via Bluetooth and the app is able to give you a rough estimate on when you'll be sober again. The device will cost $150 (approx RM400) and will provide you with stats and analysis to give you an idea of how well you hold liquor. Obviously, getting behind the wheel when you're drunk is a bad idea.
