Nokia's decision to remove the feature rather than seek necessary FDA approvals speaks volumes about the customer support you can expect from the company. Since acquiring Withings, Nokia has made a hash of the software that integrates with this scale and other Withings products. With this change, there's no reason to consider the Body Cardio—and there's no clear reason to consider ANY Nokia/Withings scale, as there are far cheaper options with the same effective features.
Now to the scale. It is well designed but not very different esthetically that most models. It is accurate regarding the weight measurements and the heart rate measurements (as compare with a blood pressure monitor and a sport watch), not so with the body composition measurements, in this case it might be useful for having a rough estimate of the actual values and a sense of the longer run trends but do not put much faith in day-to-day variations much less intra-day ones.
The body composition measurements are actually indirect ones based on the resistance to an electric impulse between the contact points which varies with the level of hydration and the type of tissue (muscle contains the most water, bones the less, fat tissue in between), this measure is used as an input in an algorithm along with your age and fitness level to give you an estimate of your body composition. This scale is the simplest as the contact points are only on your feet, others also have a handle that provides contacts through your hands and supposedly are more accurate because the electric current runs through your entire body.
What I have found is that this scale is more accurate at measuring the hydration level and its algorithm is probably unsophisticated with the most simple correlation to derive the fat, muscle and bone percentages. For example, I am a very athletic person and I work out hard four days in a week on mix routines of cardio, weight training and core exercises. As a response to the stress my muscles gradually retain more water so my weight goes up slightly during those days and usually shot up on the last day because I go to work on my job after the gym and the lack of rest means a higher stress level. In my off days my weight goes down to were it was before, in total an oscillation of 1.5 to 2.5 lbs up and down in a week. The scale though translate this couple of pounds of water up and down as losing and gaining a couple of pounds of muscle and sometimes a couple of tenths of a pound of bone mass plus minor random fluctuations of body fat. Obviously the only thing that change is the water which is though accurately reflected in the percentage shown by the scale. Another example, at my 61 birthday my body fat shot up 1% just because that is an age threshold in the algorithm so I went from 9-10% to 11% in one day and stayed there. I am not going to say this measurements are totally worthless but they only give you a very relative picture of where you are and the trends and nothing more. You decide if that is worth the extra money you will pay for this scale.
Cleary on the plus side is the fact that this scale with the companion app and web page keeps track of your weight and automatically syncs it with some other fitness apps which use it to calculate more precisely how many calories you burn and makes it easy to share with your doctor, trainer or health insurer.
I have no idea how accurate was the now gone pulse wave feature but I found that it roughly correlated with some stressors like lack of sleep or rest, jet lag and such. The battery life is very good, to will last at least 6 months of regular use but I don't like that the battery is not user replaceable so once it fails there goes the scale.
In a nutshell, with the unique pulse wave feature gone it is just another one of the many body composition scales in the market and not the most accurate at that although I suspect that most will have the same shortcomings.
