So many positive posts on this. But I have to say, it sucks! the weight is highly inaccurate. It has NEVER given me a bodyfat% measurement. Multiple emails to support with no resolution. The forums site at Withings is filled with people having the same problem. Will probably send it back for a refund.

Good heads up. just curious, what scales have you (or other people) used with highly accurate results? I have a taylor that really seems like crap to me too. I can weigh myself several times in a row and get different readings with a 2-5 lb variance. I’ve also noticed that depending on where you step on the scale it will weight differently (more towards the front = heavier, back = lighter). The measurement on a good scale shouldn’t matter where/how you stand, if your weight shifts etc… The bodyfat % on it seems wrong too… I have no way to tell objectively, but I can clearly see I’ve lost weight and gained muscle, and it onyl went down 2% for a week and then went back up to where it started. I’m pretty sure it’s gone down though…
I was looking at some of those Tanita ‘body composition’ scales, but 150-200 seems pretty steep for just a scale! anyone else out there have a really dependable scale?

I have an Omron bodyfat scale. The weight seems accurate. (Step on several times and the weight usually only varies 0.2-0.5) Body fat I can’t speak to. I do not have available “Gold standard” to test it against. So I just use it to view trends.

Those scales are all way of sometimes. The variation in weight has something to do with the position of the scale on the floor. It has to stand on a flat stable surface. If one of the four legs is not quit as stable as the others you will have strange weightreadings. The bodyfat readings depend on electrical impendance and measure typically from 2 points e.g. the lowerbody. If you read a manual very carefully(wich is though for us guys) it gives you very rigid instructions on how and when to measure. The variation in the BF readings from day to day have a lot to do with how hydrated you are how long you are out of bed etc. When you get to lower bodyfat levels it will act strange again and then they provide an athletes mode. On the Tanita you are an Athlete if you train 10 hours or more a week and have a resting HR < 60. Just flipping the switch will lower your BF by 4 a 5 %. As Trollund says they are just good to see a trend (and only when used under similar circumstances). You do need to give your lenght, and age because when you get older it gives you automaticly some BF extra because older people tend to have more internal fat around the organs.
The best and cheapest way to measure BF is to buy a set of calipers. The are around $ 20,— and give you a pretty good reading.

Thanks for the info guys.
In my case I definitely think the scale is just poor quality… In general I know most of that stuff you mentioned, but my scale is on a hard, flat surface, and is very stable where it sits. I don’t see any reason it should give me different readings when I stand on it less than 1 second apart with no change in the scale’s placement…
As Trollund mentioned- I know the bio-impedance scales are not very accurate, but I was also trying to /at least/ use it just to track a trend vs getting a fully accurate reading, as I know those scales are not equipped for that. To help cut down on the variation I weigh myself at the same time every day- first thing in the morning (after going to the bathroom). It also reports water% (although the accuracy of that could be off too), but it reports pretty much the same every time, so I’m thinking there’s not too much variation there. I know I’m losing body fat, just because a lot of weight has come off, I can see it, and my strength and muscle size seems to be increasing- so I don’t think all that weight I’ve lost has been lean mass, although I guess it’s possible…
For accurate body fat I may get some calipers or try that bod pod thing. But I’m really looking for an accurate scale that won’t give me multiple pounds of variation when standing on it a few times in a row, and hopefully at least a little more accurate body fat so I can look at the trend.

all the logs are pretty out of date actually. I used to keep up with nutrition logging better, but I’ve never been good with workout tracking because to me it just takes too much time to enter everything. I do the exercise bike about 5-6 days a week, and about 30-40 min of weights 5-6 times a week. That’s why I was saying I saw strength and muscle increase- I’ve been going up in weight for most of my lifts, and I can visually see the difference too. For body, calipers are probably the most accurate for the price value, but for body weight It would still be nice to have an accurate scale that will give me consistent results when weighing multiple times right in a row. If you have to spend big bucks just to get that, I guess I will- but that doesn’t seem like it should be a lot to ask from a scale!

I think the withings scale is pretty darned inaccurate in measuring bodyfat simply because the results fluctuate fairly wildly from day to day even though I measure myself at 5:45-6:00a.m. every day. By fairly wildly, I mean by 1-1.5%.
I have been maintaining a caloric deficit, not an extreme one, for several months. The weight is coming off, my waist is shrinking, but my my Withings bodyfat has only dropped 0.5% when, for the same period using the navy method, my body fat has dropped down from 19% to 17% .
I don’t think a drop of 2% when using the tape measure is adequately represented by the scale which shows a drop of 0.5% for the same period (and if I used today’s reading I’ve actually gained 1% body fat according to the scale.
No home-testing method is perfect. The scale may be fine for spotting a trend over a sufficiently long period of time, but I honestly don’t recommend it for measuring body fat and lean body mass. I like to know from week to week whether I am losing LBM or not, so that I can adjust my caloric intake. I don’t feel that I can trust the scale’s measurements enough to base my calorie decisions on its output.
There are too many variables – how hydrated I am, what is left in my digestive track, where I place my feet on the scale — all of which seem to impact the results and cause me to doubt their accuracy. However, I do like that it tracks my weight automatically. Wish it was better, but I do like the weight log.

i use the BodyTrace eScale. it is super cool, simple as it should be, i’m not interested in any super high tech stuff. it looks good, it is accurate and it worked from the 1st moment i unpacked it. i tried the withings scale but the setup is just over complicated and it does not work well.
BodyTrace’s log is super cool and they have a food tracker (i played with it a couple times) too for those who track their diet.
measuring body fat % is a whole other thing. i think anyone who’s interested in that should buy a dedicated device to measure your body fat, as no weight scale is going to give you an accurate number and that is simply the truth about it.

I have noticed that there must be some RF (Radio Frequency) interference between the refrigerator and the Wiithings scale. I am an engineer so I know that it must be RF interference instead of, say, powerline interference. I have noticed that the more often I open the refrigerator, the more inaccurate the scale seems to be. IN fact, if I frequently open the refrigerator in a day, the next day the scale seems to read unexpectedly high. I am wondering if anyone has had this experience and whether we should report this to Withings ?
