The balls have a surprisingly bright light is many times brighter than the balls of practitioners and Co. The burn time is well lit up late into the night. Needs improvement is the attachment. The "skewer" no longer hold the balls in a little more wind. I have an M10 threaded rod screwed in place the skewers and now also keep up to wind force 7-8. The screw without a tool by hand possible. Absolute buy recommendation
