I was using a beaded chain I bought online and the grippers kept sliding off the stems of the glasses. Irritating! So I bought these and love the lightweight material and all that slipping and sliding nonsense - gone! Unfortunately I lost my glasses at the beach, but I ordered 2 new chums so that I will have a backup in case that happens again. Great product!
The Adjustable Orbiters work fine but my surgical loupes have thin plastic temples. I've tried a number of options for this but what has worked is cutting a piece of Gorilla tape to fit, then wrapping it around the end of the temples several times to thicken them up. The Orbiters then slide on with suitable wiggling over the Gorilla tape and stay in place.
Delivery was really s-l-o-w, (2 weeks... really??) but once arrived I was quite smitten with this product. Micro cables are a very discrete way to keep my slippery glasses in place.
Sorry, can only give one star - you show order fulfilled, order never arrived. :-(
Great retainer! Sit comfortably on the glasses and sit securely. Highly recommended
