Simple and effective. 54

We bought this watch after our resumption of sports activities with my wife.
Contrary to some comments, the Heart Rate Meter works perfectly on our wrists, despite sweating due to port "tight" of the watch. The GPS grip is also extremely fast (a few seconds to 30 seconds). Finally, it is not necessary to remove the watch from the wrist to recharge / acquire data, as opposed to what we have read in some reviews.
The watch is easy to set up, the screen is easy to read during the race and it is easy to change the parameters displayed according to your interest.
The only downside was the creation of an account on tomtom mysports because the data is not recoverable as via a connection through USB. We almost returned the watch because it was impossible to create an account regardless of the computer, the operating system or browser, which makes the watch almost useless. Finally (and why) we were able to create the account on the dedicated website, racing data are then transferred fully usable.
The other improvements to make (but minor) would be the ability to have multiple profiles on the recordable watch, even if it's fast, it's a shame to have to change the information of the user when shares watch.

In summary, we are very satisfied with our purchase, plus a significant number of software is available to use the data. Moreover SHIFT (which have already started) of the watch and software will improve the product.
