Bad design: Jailin Fan Cold and hot faucets. [taps] The hot (left) and the cold (right) water faucets are separate. Now, for the life of me I don't understand the logic behind this (I had the same problem one years ago in London).

Good design: Jailin Fan Oral-B Toothbrush It has got timer. Bring very good experience of brushing teeth to user.
Good design: Grace Chen I think the design of the light controler is good. It is simple but easy to understand.
Bad design: light switch What can you do with this switch? Lights on Lights off How to tell the difference? Dim the lights

Bad design: Judith Borghouts Jura Ena espresso machine ‘After years of using it, I still can’t remember how to do certain things.’
Pratyush Pandab Students in Langwith Uni accommodation might agree with me. The induction cooker with 4 hot rings arranged in a square panel and their corresponding knobs aligned on one side of the panel. Its always fun to watch my flatmates turn the wrong one and then realize it later and mumble!
Bad design: Grace Chen I think the oven icon is not very good, I am not really understand what does it mean.
