My green one is only 5mW...and visibility is fine. 100mW ones were considerably more expensive. Yellow one does look good tho'
Second mount arrived - the GoPro-type one - but it doesn't work. My idea was to use the handlebar mount I have to grip the laser - only problem is both it and the mount that arrived are the "female" fitting, so won't bind together. Pity, a bit of adjustment would have been helpful....
