Replacement Fabric Headband for SleepGuard Biofeedback Headband - Adult Unisex - 1 Count (Pack of 1)
S**A
Just what I needed for my biofeedback device.
After awhile these headbands loose elasticity, then you know it's time for a replacement. Mine usually last 8 months, but I'm sure it's different for everyone. Just use your own judgment.
