Title: Great random number generator
Review: If you're looking for an inexpensive device to generate random numbers, the HBF-306C is ideal. But if you're trying to measure your body fat, its pretty useless. Despite following the directions and taking measurements at the same time every day, the numbers displayed fluctuated all over the place. My intent was to use this as part of diet program where during the weeks when my weight didn't go down, I'd see a change in fat percentage. But, despite losing about 25 pounds over the better part of a year, and having ample visual evidence that my fat percentage was lower, the HBF-306C gave me no useful information. Possibly other techniques such as ultrasound or caliper would have given better results; I didn't try either. But this gadget was definitely not worthwhile.
