Question for Contour HD owners:

I am undecided on purchasing a second Contour HD at Amazon for $138 as compare with the new Contour Roam. I really don't mind the internal battery, but more concern with water problems. I have yet to test my old Contour HD in the pouring rain but it did ok in light rain or shower. The new Contour Roam claims to be much more waterproof.

So have anyone used you Contour HD in bad rainy weather? Did any water got into the control buttons, card or battery?
