I took my new runbell out for my rainy Monday morning run, trialling which hand to put it on and which way round. I found that when running the position of my hand meant that I could not fire the ‘pinger’ with the thumb of the hand the bell was on.
This is because the bell is mounted squarely on top of the rings, so that my thumb couldn’t get up and over enough to pull the pinger down and allow it to spring back and strike the bell.
If the bell were rotated around the ring by 15 degrees or so it would be more accessible. Instead I found I could ring it by wearing it inverted, with the bell inside my palm. This muffles the sound a little bit but does mean that I can fire the pinger by flicking up with my thumbnail underneath it instead of reaching over and pulling the pinger down and releasing it.
