Great for Road, not so much Off Road

I've put it through the wringer
True to size

I've used Karoo 2 for five months now. It has may great features, especially the screen. However, it is heavily weighted towards road riding. It's off-road maps don't include contours/topography and the trail names are either non-existent (until you zoom all the way in) or very small and difficult to read (again, they're only seen in full zoom and even then, the text is small and discontinuously shown along the trail).

Best on the Market

I've put it through the wringer

I purchased the Karoo 2 last year. It is nice to see that Completive Cyclist has it. They are always updating this beautiful piece of art. The Karoo 2 is hands down the best and giving Garmin & Yahoo a run for their money. Does hesitate and just get you one, I promise you will not be dissatisfied

Great GPS

I've put it through the wringer
True to size

I've owned a Karoo and now the Karoo2. Love the big clear screen. GPS for exploring is better than on my Garmin. One thing I do miss, the Garmin does a much better job with live tracking so people can see where you are. However, riding ad-hoc routes and making changes to your route on Karoo is much simpler.
