These make badminton really fun and aesthetically pleasing when playing after sunset. The fact that they glow in the dark is great for late afternoon games or matches. They seem pretty darn sturdy.

Good birdies, slightly heavy due to lighting load. Work as good as the more expensive brands i've used in the past. It's nice that they're decent shuttlecocks at a fair price.

Lights last a long time, way beyond the 48 hours listed on the box. Sometimes they turn off from hitting so much but if we adjust the on button again, they still work. Even if they aren't bright, they are still functional during the day.

Extremely heavy and is not the weight of a standard birdie. The lights rarely stay on.
