my favorite thing about it is the calorie tracker i have in it (although I haven't really been using it much). it has a list of thousands of common food items. all you have to do is put in the amount that u eat of that item and it automatically calculates teh calories, carbs, fat grams, protein, fiber, etc etc. and u can easily add more items to the list to choose from... you can calculate ur BMI, BMR, your body fat (although it is somewhat archaic), keep track of blood pressure, calculate how many calories u need to cut back to lose a certain amount of weight by a certain time based on ur BMR. it is a great weight loss tool. a much better bargain than those calorie calculators I see around walmart and on infomercials.

I am in no way affiliated with www.buy.com , I just shop there for the best prices.
