Granted this product is convenient and cheap, but that doesn't offset it rendering data that is misleading and potentially dangerous. I am 6ft, 175Ibs have a 33" waist (around the belly button), workout 4 times a week (running/weights) and this little device consistently tells me I have 28% body fat. It's saying that of my 175Ib frame about 45Ibs of it is pure fat. Absolutely ridiculous! I'm actually much closer to 15% body fat based on more accurate devices. I mentioned "dangerous" in the first sentence because some might actually believe the numbers rendered and go on crash diets or meal/supplement plans.In my opinion, this product is not worth the $20 I spent and I do not recommend it. Wish I could find the receipt so that I could return it.
