I am a personal trainer and a coach and the RW2 has been my ideal watch. I have invested in other expensive watches and been disappointed by their features and by their shortfalls when I have tried to use them in coaching and sporting conditions. This watch has had none of those disapointments. Before I invested in an RW2 I sent an email to the manufacturer to ask for details about its function and all those questions were itemised and answered promptly. I also found it great to be able to download and read the instruction manual before my purchase. I live in Canada and the watch was delivered quickly and easily. It has functioned flawlessly ever since. The online tutorials were great and the instructions were thourough but not unintuitive. I could not be happier with my investment in this watch personally or proffesionally, and I have recomended it to others ever since I got mine.
