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). In the current configuration, either your hand is really cold or boiling hot - but never in a happy medium (no Intelligent Design here!).
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
Poor design: Cash dispensers: Martin Rooney + Alistair
Cash dispensers: Martin Rooney When I go to a cash point, I am 99% of the time just wanting to get some money out. So my mental model is that I expect to find an option simply titled 'cash'. But (as this screenshot shows) there is often never just an option 'cash', its always coupled with some other stuff that I don't care about, that just waste my time and forces me to stop and think. In the screenshot I can choose between: Cash with on-screen balance Cash with receipt Why not just cash ?
Cash dispensers: Alistair Inconsistency Allows me to enter how much I want before it tells me its empty Offers me amounts that are multiples of £10 – and then says it’s only got 20s An unusual document mix may be dispensed

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.
