- Easily replaced (i.e. by a common household object)
- Extremely situational
I can think of two right now:
1: A faucet which you tap with your arm to turn on/off. They claim it's because "sometimes your hands need a hand" and they show people with insanely exaggerated portions of sticky mass encasing their hands and tapping the faucet with their arm then washing the stuff off. The water would always come out at a fixed rate (I think), so you wouldn't be able to turn the pressure down/up, and I can already turn my faucets on with my arms: it's called applying force to the knob.
2: A hands-free, motion-sensor soap pump. You put your hand under it and it dispenses soap/hand sanitizer. This is because you don't want your sloppy mess to get all over the pump. Because you know, we all hate getting our hands dirty right before washing them.
So what were the worse products you've seen advertised?
Figured this picture might be considered relevant, also.
