I ordered the Canyon lights and they turned up today just in time for a local TT so I thought I'd test them out (lights are required in CTT events).
After the event I had a ride round to test them in the dark and brightness seems pretty good to me. I'd say the front is a little heavy – it uses a glass lens. The front mount is solid, although there was a light rattle over a couple of rough bits of road, but nothing major. The rear mount didn't feel as solid, but didn't move at all so it's fine.
I've been really pleasantly surprised at these lights because they were bought as they looked vaguely aero and to fulfil a rule, but they've turned out to be actually decent lights.
The cost isn't too unreasonable compared to a lot of other lights. It doesn't have the power of the front light on my commuting bike, but that is probably as aero as a brick.
