This is my second Suunto running watch; it replaces my Ambit 2R. I purchased the Ambit3 because the HRM chest strap that came with the Ambit 2 broke (the electronic "guts" still work fine; the problem was a small piece of plastic on the clasp, a known issue that Suunto seems to have remedied)

Costumer service was prompt and very helpful in providing information and updates on correcting this problem
