Perfect size. If you want something that you can use to keep your glasses from sliding off of your face this is it. Great for everyday use. Easily to hide beneath your hair, so no one knows your wearing them. The strings are a little larger than they seem to be in the photo, so be aware of that, but it hasn't caused me any issues so far. I wear large to extra large hats so this may not be for small heads if you want to keep your glasses close to your face. I only have about a half of an inch of space left when I'm wearing them. I usually wear 17 inch necklaces and when they are loosened up all the way it sits right about where my necklace usually sit, near my shirt collar, but this might varry depending on the kength of your glasses. I will say that adjusting them is not instant, it takes a moment to take the glasses off and on using this strap. That doesn't bother me, as It likely means that the glasses strap will stay taught and not slowly slip off throughout the day and they are not difficulty to adjust. I also usually keep my glasses on for a few hours at a time or most of the work day. I've only had these for a day of so do only time will tell how they hold up, but they feel durable. Overall this was perfect for my purposes. Keeps glasses on my face, The strap can be hidden, & does not irritate my head with excess weight or tension.

These are pretty slick. They are a bit short and don't offer the necklace experience of similar products, but if you're looking for a simple device to secure glasses to your head, look no further!

Daughter loved these for her basketball tournament. They were easy to install and fit comfortably around her head. She’s 9 and doesn’t like sports glasses. The only reason for 4 stars instead of 5 was they say for kids but were a little loose and we couldn’t get them tighter.

work just fine, I got a big head and these fit very well

Great product durable and very handy

Not the best not the worst - They are super easy to adjust HOWEVER even at the smallest setting they were still way too big for everyone in the house, adults included, to be the least bit functional.

These straps definitely helps to keep your glasses in place without falling off your nose. You can also adjust the length of the strap to tweak comfort, whether it's loose or tight. It comes with three straps which I owned two reading glasses and one sunglass. Other than that, comfort was comfortable, doesn't feel extremely too tight, it feels right and it doesn't tend to fall off my nose too often which I'm really happy with this product!

I really like these. They seem well made and do a good job of holding onto the glasses. However, I wish they were at least a couple of inches longer. When my glasses are hanging around my neck, I wish it was a little further away. Great price for 3
