The Pulse O2 is compact and makes a high quality impression. The idea to insert the Tracker in the bracelet is a good idea. Here we come to the first deficiency the supplied strap, rubber in its purest form without sacrificing quality. I now exchange this against a commercially available leather strap, the arm makes the supplied belt no good and pleasant impression.
Since I already have a Withings scale and a blood pressure device blends the Tracker 100% in the data world, a coherent overall solution.
He will track steps spilled meters, altitude, calories, pulse / oxygen in the blood and to sleep. Here the Tracker does a very good job and is accurate and comprehensive. Second negative point is the readability of the display in the sun, is probably not intended to be read under the sun :-).
It synchronizes very well and independently throughout the day. The data connection is stable and very fast.
The battery power I have to test yet, I complete when new findings here in the Review.
The first impression a very mature device with much strength and very few (verschmerzbaren) weaknesses.
Supplement 3:05:
Unfortunately, the device is broken since yesterday, the display remains black, also the charging cable is nothing more
After a week of use the following addenda
- Display is rather weak, the sunlight can not be read
- Sleep tracking is very good
- Unit sits rather loosely in the band that is not made for eternity
- Why is the heart rate monitor at the bottom of the device? I have to take out him every time to measure, not an optimum solution.
- The Tracker is not waterproof, the question is whether you do not have a rubber stopper for the open USB Steckeranbnschluss can offer?
I regret to say that will not be on my permanent companions of the pulses in the form.
