The Velcro adjustable spectacle strap is easy and straight forward to put on and use. It comes in two parts that are stuck together by the Velcro. The rubberized loop at its end fit over most but the smallest of spectacle temple. After which the user will have to estimate the desired fit and stick the Velcro together. There are no loose ends once fitted and the straps can be easily released by pulling the Velcro apart.
One of the biggest drawbacks in this product is its rubber ends. They are chunky and when the temple is adjusted properly to sit close to the head, the rubber ends will get in the way. The Velcro is also very stiff which causes it to sit higher on the head especially for library/straight-arm temple. While it be very good in keeping the eyewear secure, it is not very comfortable to use.
