- Has several colour variations by mixing R, G, B, W. You can also auto rotate the variations.- You can halt the projection or speed it up/slow it down. I think there are 4-5 levels.- You can turn on/off the green stars.- You can connect to bluetooth (check bottom of projector for product code) and it'll auto connect after that each time so you can listen to music, podcasts, anything through your digital devices.- You can pick out of a selection of soothing sleep tracks.- You can change the brightness, 4 brightness settings. Every setting keeps the room relatively bright even on lowest but like a mood light. I'm really sensitive to light but I've slept well every night since I got this.- Sleep timer 1h/2h, and eventually turns off after a few hours. Idk how long tho 'cos I always fall asleep before that.- Battery is secure but easy to take out.CONS- The remote needs to be really near the green laser area I think? Either way, it needs to be really close to some part of the projector so it doesn't work super responsively. It's not strong enough that it'll accidentally work on the TV like the warning says on the remote lol. Haven't had trouble with it because I don't use the remote too often.- No brainer stuff but the globe area of the projector is large and the light is bright so if you don't put it where it'll be shielded from your eyes, it'll be an eye sore.- Again, an obvious thing but you need to put the projector in a way that the light gets to hit as much surface area of your ceiling and wall. If there is anything blocking it, you'll only get part of the wall or ceiling. E.g. During the day I set it behind my laptop/laptop stand so I get to see it on the wall behind it, but at night I set it on my desk chair and swivel it around so I don't have to look at the light and it still hits most of the ceiling.I have this connected to my laptop and for some reason, even after it's turned off, it automatically turns on when I turn my laptop on. So this has helped me remember to keep this on when I go to sleep. I have chronic insomnia so I don't fall asleep late and I sleep very little. But since I got this, it's helped relax me a lot in bed just staring at my ceiling. It's really nice. I think everyone should have one, tbh. The streaks are sci-fi like or remind me of Northern lights and though the patterns don't change it's soothing enough that it hasn't gotten old.I don't like spending money and I don't like getting random things I don't need for my survival or well being. But this one I don't regret because it's helped me relax and it makes my room pretty without me needing to buy random stuff to spruce it up.The lights are prettier in person, but the photos make them look more vivid. In person they somehow feel different every day, probably cos the way I position is (as I move it daily) changes slightly, but also the way the colours interact when on auto rotation is really awesome. Sometimes it cuts to the next colour palette in an abrupt way but it doesn't happen often.I don't really have time and energy to leave reviews, but I wanted other ppl to know to get this because it helped me to see the reviews of ppl getting a lot out of this product. I purchased this at C$39.99 on 20% discount and it was worth it at that price though a little expensive. At 50, it would've been too expensive for me and not worth it. I also gave 3 stars for giftable because the box it comes in isn't pretty and it looks like one of those Aliexpress-type ones, the Chinese mass-manufactured boxes lol. The inside product was well secured though.
