This is the best vibrating watch you can purchase. The stylish watch allows you to either set up to 12 alarms at any time during the day OR set the watch to vibrate at specific intervals like the VibraLITE. Method used to set this watch makes it difficult for children to inadvertently change settings. The easy-open battery compartment is a real benefit over all of the other watches that require special tools or trips to a jeweler. Keep in mind that vibrating watches require more battery power and several batteries each year. The watches fit a wrist five inches in circumference or larger. Remember that ALL vibrating watches are approximately the same size (1.5 inch diameter face) and function is more important than style.
