Useful item
These arrived on time and look a little more sturdy than the Peeper Keepers I purchased previously. (One of those broke within 24 hours, the other within a month)  So far these are holding up.  My only criticism is the adjusting mechanism is just a metal spring and it keeps coming loose so they slip down. I haven't used the device to hold them tight on your head so don't know how well that holds up.  I wish they were just two inches longer at the maximum length.
