If you can get over the fact it only projects green stars, this is the best night sky projector you can get.
16 February 2018
I bought other night sky protectors and they were rubbish. They failed to project anything onto the walls or ceiling despite claiming they could. Even best selling 'projectors' on Amazon!
As a rule of thumb I'd suggest anyone avoid usb powered or battery powered projectors and they juts don't have enough power to project anything at all. I ended up buying this despite it being more expensive than any of the other I found, but have no regrets at all. It's incredible. It's very powerful, the projections are very high quality and bright, really beautiful. I massively regret not getting this in the first place.
My only real criticism is that it only projects green stars. I really had expected to be able to change or cycle through colours, at least the option of white stars, but no it's green or nothing. The 'cloud' effect is blue only which is fine, but it feels more like the aurora borealis than clouds, or perhaps the reflection of a swimming pool. Either way beautiful. But it really would've been nice to have white stars, to feel more like an actual night sky. It's just too artificial looking being green which is a real shame.
Also there's a slight hum of the motor, which is very subtle when set to static sky, or slow sky, but more noticeable when on fast mode, or if you're trying to use it while you sleep (which I wouldn't do as there's no auto sleep timer). But it's really not a problem for me.
