The mount it comes with isn't very well reviewed, but I haven't tried it yet. As it fits a GoPro mount I've just fitted it to the bottom of my Barfly Garmin mount, which is very neat and gets it off the bars. Means the light is upside down, which isn't ideal for the beam pattern, but it's bright enough that it doesn't seem like too much of a problem.
Battery is easy to replace, so should be possible to carry a few for longer rides if you can find somewhere that sells them. Also has a lifetime warranty.
If anyone is on the lookout for a bright front light the Blackburn Central 700 is going fairly cheap on Ribble. I bought one a couple of weeks ago: http://www.ribblecycles.co.uk/blackburn-central-700-front-light/
