I ordered the Sigma test for 4 weeks before and can now highly recommend without hesitation.
I after a year's break (volumes crack etc ..) have again started running this year, I wanted to buy myself a heart rate monitor to get started.
But since starting with GPS etc ... the clocks until about 100, I have opted for this.
My normal running track is a forest track with about 2.5km per lap. Here the lap time function of the clock comes into its own.
With the Pulse I previously had no problem finding just the belt moisten (spit or water), and measures.
The only minor complaint:
The data can not be transferred to the PC. But here you can also manage themselves by their own small Excel file is created.
