Bought for a 10 year old they were too small to be comfortable for him. Saved them anyway to use for a younger kid. The product still has a solid value. The included case feels well made and sturdy, but not strong and unstable to shocks. Also included is a small multifunctional screwdriver and a cleaning cloth. The included blue light and test card were a nice feature. For those who are unsure, shine blue light through the lenses of your glasses at the test card from a few inches or less away and you will see that the test card does not change color because the blue light is being filtered through the lens. If you shine directly at a map without glasses, the map will turn purple. I've tested this with some expensive blue light Rx glasses and with a much more powerful blue/ultraviolet flashlight, both glasses filtered blue light equally. The lens of the product's goggles is not entirely clear or rather colorless, it has the slightest yellow cast, but it is imperceptible unless you are looking for it and can be more visible in cold light such as neon light.
