For luminosity and duration one can only say: madness. I bought the glow sticks for a party and thought that does not keep them too long, as is the case with most glowstick. But this Starlights show quality at the highest level. The glow sticks so bright and light up as long as I was not previously known. Could not be better.
The various connectors that were included with, you have to mention positive. Through these connections, the creativity knows no limits with the glow sticks. While our Party a creativity contest is even spontaneously arose which showed that the glow sticks can be formed into very many great new characters and plugged. Prima.
As already sounded one can here only awarded 5 stars and shopping safely. Could not be better!
