Good, but use at your own risk
The suction cup is pretty sweet- let's you capture great time lapses and action where otherwise you wouldn't be able to. But, although I believe it stayed on the F1000 race care, it's not a sure thing. On bumpier rides it can definitely work itself loose. Also, I've experimented with it a bit as a ski or snowboard mount, and it can't hang in that environment. So, as long as it's in a place where it can be recovered when it falls off (i.e., not a boat) go for it.
