I wont buy a toaster just because its design matches my decor but can't even do basic toasting...I would rather buy/have an ugly toaster but can toast bread like yakun kaya

At the very least it has to do what it’s supposed to do effectively and efficiently

Even though it should be function sometimes you are attracted to design as well

Function mostly. If it looks better it's a bonus point!

design doesn't matter without the function being there

If same function & quality, better design then wins

Its durability and functionabilith

Sometimes the design of it as well

Function, then whether its compact

Both but function most important
