The previous negative reviews I can not understand for the most part and did not understand. Here I have a feeling that some users but had excessive expectations of the pulses that he ever can fulfill course in any way. But let's start at the beginning.
When I got delivered on 16/08/2013 the small companion, I have only once fully charged him. That went relatively quickly, but the built-in battery is now being expected not too big. Since we're on the battery, it keeps definitely before what promises to Withings in its technical data from the Pulse. Today I have if you count the initial charge, charge him only the second time or the third time. The pulse is with me every day in use, measures approximately 5 times a day my pulse and monitors each night my sleep. Battery performance is therefore for me more than just ok.
The function of the step counting works well almost perfect at least for me. Every now and then I count to check simply times a few steps (so 150 - 200), and so far I have the Pulse yet able to demonstrate no deviation of more than 2 to 3 steps. So the function is impeccable.
The measure my pulse, I feel as correct, at least when I compare the values with my stationary Sanitas Blood jerk meter. These voices always up to one or max. 2 beats match.
To sleep monitoring I can not say much all because me a meaningful control mechanism is missing here honestly. The only thing I can control is my awakenings, when I eg at night time on the toilet needs. These previously agreed definitely Whenever I have checked it. If and when I now had a deep sleep, I do not know. Whether the time is always correct to fall asleep, I can not say, but at least it is not grossly wrong. Do I need to fall asleep unexpectedly times longer, so I get the morning also confirmed so. Whether now agrees the displayed sleep time to the minute, I can not say.
The calculated distance traveled by the Pulse true at least roughly with me. Large outliers are not present. That this can not be 100%, should actually be clear to every user. Here are just a rough value is just delivered, and due to a lack of GPS even more is not possible. So, even here the pulses met my expectations fully.
For height profile I can not say anything. That is I think any feature that does not simply belong in such a device. The create yes not even full-blown GPS watch with barometric altimeter correctly. Too, should and must be clearly aware of each purchaser actually. For me, this feature is also completely useless and is neither used nor assume any responsibility for evaluations ran.
I also own a Withings scale, and just like with these works to synchronize with the Withings website, the Pulse just perfect. Not even I have experienced it, that no and / or erroneous data or dubbed on the smartphone or the tablet were displayed. The synchronization is quick and takes place even several times a day with no fault of their own over the existing Bluetooth connection. Well here everything works as expected.
The included strap fulfills its purpose so far without defects. Neither playing sports (jogging and cycling) nor the sleep it's been worked out or even dropped. Again, no reason for criticism. The rubber clip I have not used so far.
All in all, I can only say that Pulse I am more than satisfied with the purchase of Withings. The small particles fulfilled all that certain functions, such as can not properly tune the height profile my expectations 100% and, one should really say common sense and be clear to everyone before buying. I've finally acquired no squatting precise medical device.
