As I understand it, over in California some ambulance chasers convinced a judge that "she could have been still alive if only her computer would have displayed the correct number" is a good enough argument to sue the Evil Megacorp whose legal dept. took the cheaper way out and settled like everyone expected. AFAIK Suunto offered free testing and replacement to users living in the jurisdiction where the above lawsuit took place, but nowhere else, which to me suggest the failure rate may be well within the vendor's specs and the whole thing is a typical "only in America" class-action lawsuit story.
I have five Suunto dive computers that failed due to sensor failures. Two of them failed more than once. One Cobra failed three times and Suunto is always expecting me to pay for the replacements. Suunto's customer service and products are a piece of fish manure.
