Bests & Worsts Reviews from Amazon

This is a fantastic product. Fits in minutes and the trigger (that's really the best word for it!) is in easy reach next to my gearshift lever. It's also dayglo orange, so easy to find in a hurry if you need to look down to locate it (though you should really be concentrating on braking and steering during a crisis :) ) I commute by bicycle daily and got sick and tired of idiots in cars and trucks pulling wild maneuvers in front of me. I've only had this for 2 days and already avoided a couple of near misses (turned them into wide misses) with it. When cranked to full volume it *really* gets drivers' attention - even with their windows wound up and Eminem rattling their mirrors! Way more effective than my little ding-ding bell! I've currently got it fitted into my 2nd bottle cage, but I think I may switch to the supplied velcro/zip tie arrangement so that I can strap it to my top-tube and regain my 2nd bottle cage for longer rides or a headlight battery. 4 stars 'cos I can't yet vouch for its longevity - we'll see how it stands up to a Seattle Winter! :) [edit 2012-08] Well, it gets that 5th star back for sure. 7 years and still kicking. It's been through a few accidents (one of which gifted me a titanium plate and 7 screws in my tibia) and it's still going strong, loud and clear. The "clip/bracket" broke at some time, but it's still operational, wedged in between a few other gadgets on my bar.
