Called Saris today to check on my PT. I was having intermittent power readings from day to day. Worked fine for the first 1200 miles or so then starting giving me problems. The HR strap really never paired with the computer either. Anyway, I called today and it is now at level 3 testing or something along those lines. I can't remember the exact words. Seems they just can't figure it out. I figured they would send a new one my way seeing that I just bought the thing. Anyone else have this problem?
