GPS and style TOPP - Pulse flop!

This clock has very clear strengths and weaknesses - I have intensively tested two weeks vacation, so I can probably allow a judgment. First the good points:
- Comfortable to wear
- Looks chic, is also suitable as a (sporting) everyday Suhr
- Accurate, efficient GPS (the core business of TomTom halt)
- To navigate through the works well
- The Akkulauf- and -Charging is okay.

Now to the disadvantages which meant that I finally gave the clock back:
- The pulse measurement is far too unreliable: She sat at longer runs before half an hour completely out, then - without that I have changed somewhat - to reinstate (!). Although the measurement on the wrist spared the annoying chest strap, but it is natural for the E ... if only intermittently ever measured. In these watches category has with respect to the pulse measurement - however expensive Adidas Run Smart clearly in the lead! When you do the GPS measurement, however, is a lack of accuracy and the battery life is very low (2,5 - 4 hours at activate Bluetooth).
- The evaluation and configuration options are fairly limited
- With extended wear (in the summer) to get but including very sweat.

So: Nice try with potential, but not a realistic option at the deficiencies in the pulse measurement.
