Fantastic for keep a toddler's glasses in place!
We got two pairs of these to replace our son's Dilly Dally straps that he received with his glasses, and these work MUCH better. They never come unsnapped like the ones that came with the original glasses, and our two year old doesn't even notice they are there. We absolutely love these straps and will probably buy a couple extra to keep in reserve just in case one gets too dirty or damaged - you never know what kids are going to do.
