## What is TKL Safe & Sound?

Musical instruments can be easily damaged by large and rapid changes in humidity and temperature. Now you can protect your investment by simply placing TKL's Safe & Sound sensor with Blustream Technology inside your case.

Safe & Sound uses a patented Bluetooth sensor to provide a constant stream of temperature, humidity, impact, motion, and proximity data to the free smart phone app to alert you of hazardous conditions that can lead to diminished playability, costly repairs, and lost value of your instrument. When your Safe & Sound sensor detects dangerous conditions, notifications are sent to all your devices allowing you to take corrective action before damage occurs.

To completely protect your instrument from the damaging effects of humidity, reorder your favorite humidity protection system directly through the app.
