Yes, it's absurd, we know, but boy is this gizmo a blessing in 1970s white plastic disguise or what! Stumbling to the lav at night is one of life's little irritations at the best of times, but what really makes it so darned annoying is having to half blind yourself in the process by turning on the bathroom light. You could almost get away with going through the process without truly waking up, if it wasn't for the 'Oh my good god, who put a 1000 watt bulb in when I wasn't looking' experience. Well now, thankfully, that whole snow-blindness nightmare is finally over. The Lavnav (great name) is a joy to behold. You simply stick it on the inside of your lav lid (comes with sticky pads) and hey presto, whenever you stagger into the bathroom in the dark the motion sensor fires it up, and it shines a gentle guiding light into your lav, and turns off after you leave. It even knows if the seat is up or not - red light for up, green light for down. A brilliant, if slightly odd, product, and an excellent solution to prevent you being wrenched from half-asleepness in the middle of the night.
