I was chosen as Sigma's test driver a month ago and I have since used Sigma ROX 10.0 GPS. I find the cycling computer to be of excellent value, especially if one already owns ANT+ sensors. I dislike Sigma's ANT+ speed and candence sensors as they are not integrated in to one unit. Also bar fly mount called The Butler is not as good as Garmin's because the computer is not leveled with the stem.
One thing that needs to be considered before buying the unit is the Sigma Data Center software which is installed locally to your computer. All your data is then stored locally (bulk uploading to Strava is made very easy though) which can be either good or bad thing, depends on your ideology. I find the software to be actually pretty good (especially the mapping feature is best of breed), although a bit engineer-driven.
