I bought the clock with the PC-Link device and must say I am very satisfied damitt. I have not so much to test the functions of the clock but the setting and the Traingsfunktion with pulse recording and so too does the upload to PC work well. The only thing I noticed now that the weekdays are displayed in English ... but not really disturbing. What I have read in the comments that the chest strap receives no connection is probably because that the individual has "thick" piece of the belt has wetted and not two contact points on the left and right of it, if you get this just a little moistened one display within seconds the pulse :-)
Want Highly recommended for people who pursue their pulse on training and free time and keep it longer or more detailed analysis.
