Found this in the camping section, but use it on my mountain bike.
Works well on multi-use trails: hikers and horses hear you coming. No drama.
Works well on single-track: Often blind turns, etc- other bikers coming the other way can hear me. Again, no drama. Better if everyone had a bear bell.
It's not needed (unwanted) on long climbs or downhills: That's what the magnet bag is for.
Biggest con: not easy to slip the magnet bag on when riding. A thumb switch with a magnet on it would be much better.
BTW- This bell is recommended for trail use by the San Diego Mountain Bike Association (SDMBA).
