The arm band set is an accessory that allows you to mount your BbTALKIN units to your arm. This is the arm band only. The arm band is adjustable.
You will need to install the plastic clip type mount that comes with your units onto this band to mount your unit. (Same one that goes on your surf hat and baseball cap.)
Note: Since our units are Bluetooth, the higher you mount your unit, the longer range you will achieve. Mounting your unit on your arm can limit your communication range.
From the date of purchase, the bands are covered for 6 months. Please see our warranty section for complete warranty details.
