I hate my printer. It is a printer with a scanner combined in one. This bulky printer doesn’t have a universal usability. The labels of the buttons are Korean; and, it includes many buttons which doesn’t have necessary options. Their mapping didn’t label clearly and it is hard to determine what to click when you perform a task. Also, it has low affordances. For example, when you try to use a scanner you can’t press the buttons from the printer. You have to open a program and start form there in order to use a scanner. Furthermore, the scanner won’t work if there’s no ink for the printer. This constraint makes the scanner useless when there’s no ink.
I love my small size desk fan. It is better than any other fan that I have used. It has designed very simple but has great capacity. It is very user friendly. It only contains few buttons and they are clearly visible. Its physical mapping is pretty straight forward. Although it has some contraints, it's all for safety reasons. Its inside has covered up with plastic cover and it could not be removed or touchable.
