I bought this to replace a Garmin 1000 whose screen was dying. I've done 9 rides with it to date and I'm very please with it. It's a bit smaller than the Garmin, the screen is hugely better, I haven't tried to use it in rain yet but I think there is a good chance that I would be able to follow a course, something that was impossible with the Garmin. Mapping is good, easy to read and simple, ditto the data screen. It comes with a converter to a Garmin style mount so I haven't had to change any of my GPS mounts. My only gripes so far are that I can't find how to mute the notifications and I'd like to have the climb graphic on a separate screen rather than covering the bottom of the mapping screen. You can find a very good comparison of the Garmin 840, Wahoo Roam V2 and Karoo2 on intheknowcycling.com and a review of the Karoo3 versus the Karoo2.
