Great projection, but unsuitable for children's eyes

I had ordered this projector for our little ones. Since I simply project a fixed constellation on the ceiling to find this boring hole normal lamps. These slide Planetariums are with your circular B / W projection bit hit and miss.

Basically, the device produces a great effect. Looking at the cloud for the first time one thinks WOW.
Of course it is not a scientific apparatus and real constellations there is not even.

Does not like:
The laser is too strong and our wallpaper (white woodchip), the laser points reflected too much back. I guess that is not great for the eyes, and certainly not for children's eyes. Particularly bright are 9 points that are not located
move the center of the projection.
To snooze and sleep, the fan is too loud.

Accordingly, you should consider using. I guess the game cellar makes this projector an absolute eye-catcher. For children it is not suitable.

Unfortunately, the product of GB was delivered and for the return I had to wear yourself the postage of 17 EUR. Otherwise, one has but the regulated accommodating and I got refund the purchase price.
