Longer term report ...
Longer term, I'm disappointed by the Rox 9.0. I really wished I had gone for the Garmin 305.
On the hardware side, the battery life IS excellent. However, I plug the Rox into my computer so often that I'm not sure it matters.
The mount on the cadence is pretty lousy. I've snapped two of them. Luckily, they snapped where I could find them.
The computer itself looses contact with it's mount far too often. The best cure I've found so far is saliva. The main button on the computer itself is finicky. It's often hard to get waypoints to register. The paint on the button itself and the heartrate strap is peeling off.
The new software has nice long term tracking features. But data importation is still cludgy. And there are still serious issues with consistency between logs and trips. The new axis on the software has a fixed altitude. So if you ride in somewhere "non-mountainous" your hill climbs will barely register. And the whole graphing feature becomes useless.
Vs. Garmin where there are options for tracking runs as well as cycling, Sigma comes up empty. When one invests a lot of money into a computer system, you want options and there are none on the Sigma side.
It's still a good computer. There are some issues that Sigma is not working out. I'm inclined to switch to Garmin.
