I am actually quite pleased

The Positive perhaps first:
Unlike my Polar 800 it is super easy to use. In particular, the options for multisport (eg Triathlon: Man are swimming, cycling and running before and quitiert pressing a button only one that reached the transition area Simple really as it gets.). The configuration utility simplifies the clock setting immensely and also the operation in action just goes out of hand. The size of the numbers on the display allow you to read while running and the accuracy of measurement is provided I could verify this e within my tolerance for GPS systems (about 100m to 5km), I do not know what professionals expect.
With regard to the navigation (ie. The hunting of saved routes) I can not say much that I try this summer in Finland.

Now to the negatives:
The clock is huge (compared to the Polar 800). Certainly necessary, because you could not see anything on the screen otherwise, but I found it a little getting used to. Then there is no sensor for the running shoe, which use on a treadmill or in areas with poor GPS signal excludes.
Really bad I think but not the clock itself, but the analysis options. With Polar you get a program that gives you in evaluating the courses (or trips) the appropriate tools at your fingertips. If everything goes offline and displays a everything you want to see. In Timex there even such a program, but that is quite expensive with $ 129 (ka what are in), and then the evaluation is not as comfortable as in Polar. The free solution for Timex is the website of Training Peaks. So you loads its data to the Internet high (which can be problematic for holidays abroad) and can then read some details of the session. If one has not sufficient free analysis tools that you buy the premium subscription with just under $ 120 per year is an expensive business.

Conclusion: For the money you get a great rate monitor exactly for almost every sport that delivers what you want as an amateur athlete himself. If it still would be a reasonable solution for the analysis it would be 5 star. The perfect alternative to expensive products from Polar or Garmin.
