This bell works perfectly. It is clear, easy to use, and fairly easy to mount. I have purchased two of them now, my friend's bike's handlebars are larger and it still worked but we did not use the included screw to hold it in place.
ARRIVED IN GREECE AFTER 2 WEEKS EXACTLY. JUST AS DESCRIBED AND WORKING. GOOD PURCHASE CONSIDERING THE COST OF BUYING THEM. ONLY PROBLEM IS THE COLOR WHICH YOU CAN'T CHOOSE. MINE WAS SENT WITH NO COLOR(SILVER) .
