You can actually find out the "exact" calories/fat/fiber in an item if you enter code into the scale before you weigh it. For example, say the code for a banana is 100. Enter 100 and then weight the banana. If the banana weighs 6 ounces (or 168 grams), the actual nutrition for that weight will be displayed - then you can use your POINTS finder/calculator to figure out the points. (BTW, it looks like it is metal, but it's just a silver plastic.)
