From Table 1, we can see that the three types of toaster we used are Hanabishi, Pensonic and Philips. These three types of toasters are two slide-in toasters with adjustable browning control. The adjustable browning control has 6 scales for the Hanabishi toaster while Pensonic and Philips have 7 scales. Therefore, Hanabishi's rating on this feature was slightly lower than the other two types of toaster. Adjustable browning control allows users to control the color of the bread after toasting. Toasting bread on the 1 and 2 scale will cause the bread to turn light brown while 3 and 4 are considered average. Last but not least, from 5 to 7 the bread will become dark. Therefore, users are encouraged to use the medium scale for toasting bread. Next, Hanabishi features a reset button to allow users to stop and reset the browning control for toasting bread. Meanwhile, Pensonic has the stop button. The stop button allows users to stop the roasting cycle before it is finished. The three types of toasters are all automatic pop-up toasters...
