Luminosity, color and light duration bad

I rate products generally only when they are far above or below my expectations.
Unfortunately, this article concerns the latter.
Ums briefly summarize: very poor luminosity, luminous paint badly, burn time bad, packaging underperformed. Detailed as follows:
The color is not really blue, more of a white blue ...
The luminosity is about 5-minutes MAX10 acceptable, then you can throw away, there you can see little light in a dark room is not complete yet, the break lights ...
The burn time ... as already mentioned a maximum of 10 minutes acceptable luminance, and even that little light then reaches scarcely 4h.
I often and many Starlights buy, because I often glow-stringing bring before at parties. Accordingly have a lot of experience with different glow sticks, and who wants to have something worth his salt itself seller only Green with the slogan 30min highly luminous. But these are not only not recommended in my view, I am about to complain about it ...

Now the seller Packaging: in box 10 are Starlights almost Completely restructured loose inside, made only with NEM in quickly stuffed schnürbündel halfway safe for transport. I have the same seller bought a similar product in which were even a few glow sticks before the arrival broken.
The package itself was open, possibly to cram the strings and / or to check the undamaged glow sticks ... a no-go in to send Nevertheless, in my view open product ...
