I have one.
The brochure says woman's water % reading should be at least 45%. Mine was just under, at 44.5%, so I started making a real effort to drink more water. I drink no soda and only one cup of coffee a day, so my main beverage is water.
And the reading is never over 44.5% (Tonight it was 42.6% and I drank 3 cups of water with dinner and one after!). What gives?

What is the brand? I have never seen one. I do know I don't drink half the water I should, it has really been hard for me to drink 10 cups on the new diet I am on.

Maybe you need some salt in your diet.

When I was pregnant, my midwife told me to make sure I did not cut salt out of my diet, so I would stay hydrated.

Unfortunately I have trouble trusting this type of thing. I went on a "health" binge once, skipped the pop, and drank water for a week. Man....was I sick. Guess pop works for me.

How can something measure water and fat??

Here's a blurb about one scales features:

Why You Should Monitor Body Water and Fat Percentage
If you're like most people, you're not drinking enough water. If you wait until you feel thirsty, your body is already suffering from the effects of mild dehydration. You continually lose water during the day through sweat, urine and breathing. The amount varies due to several reasons, including your physical activity level, illness, medications, poor nutrition, or even climatic conditions. Monitoring your body water percentage allows you to quickly compensate if your levels are low, allowing your body to function more efficiently. Having the right amount of water in your body will not only make you feel healthier, but you'll also reduce your risk of developing serious health problems in the longer term.
High body fat levels can reduce your endurance and have been linked to heart disease cancer and diabetes. Tanita's body composition analyzers monitor your body fat and body water levels with Bioelectric Impedance Analysis, or BIA, the same advanced technology used by doctors. Foot pads send a low-level electrical signal. Then BIA measures the resistance to this signal as it travels through the body.
The Tanita BF680W is calibrated for standard adults, children and athletes and stores data for 2 people, measuring body fat in increments of 0.1 percentage points. The scale's large, easy-to-read 2.25-inch, 2-line LCD shows weight and body fat simultaneously, and instantly compares these readings to healthy ranges based on the user's age and gender. Simply supply your gender, age, height and weight into the memory, step on the scale, and the monitor does the rest.

Very true, your body needs some salt in order to retain water. That's why Gatorade is so high in sodium!!

So, no one else has used one? I just wonder if my readings could possibly be wrong for some reason cause if they are right I am not very healthy!!!

I have a Weight Watchers electronic scale that gives hydration, body fat and weight. I have no idea how accurate the hydration and body fat readings are, or how the scale works. My hydration level is generally in the mid-40% range. Living in the desert, I drink quite a lot of water and lemonade.
