The SlapLit is just like a traditional slap bracelet, but with one very important difference - a bright, easy-to-activate LED that keeps you seen and safe at night. The LED can be set to glow or flash.
The Rechargeable version has a battery life of 5 Hours and can be recharged using a Micro-USB cable (not included)
The Lithium CR2032 version has a battery life of 100 Hours and the battery can be replaced.
