The built-in LED is available with 50,000 hours of use over the long term.

However, since it is a wireless product, the battery built into the forehead area lasts for around five years depending on the environment of use. (When used 20 minutes every day)

Please be sure to change the battery about every five years. Battery exchange services are available by contacting the CELLRETURN head office.
