I ordered a BRSTAR Northern Lights Aurora Projector' for review. It has worked well without issue. It has worked well to add a little light to a dark room and has a soothing effect. Overall great product.This thing is great overall. It's very soothing and good for gently lighting a room at night.It needs continuous power (it doesn't have a battery). It draws very little power, though, and runs through a micro USB cord, so you can run it out of, say, a portable phone power bank.I'm not sure I'd be comfortable leaving it running all night, at least without trying that during the day first. But you can turn it on for a bit and turn it off before you go to sleep, or turn it off for your kid.It has a few different color patterns and combinations. Each one basically has swirls of red or blue, and a pattern of green "stars" dotted over it. In some of the modes, the colors change, or the stars fade in and out, or both.You can tell it to move the background colors in a swirly circle, or keep them still. The movement is slow and gentle.You can also adjust through three brightness settings. They cover a good range.The projector is very wide, covering the entire ceiling of a fairly big room.There are only two issues, really. One, when it's in a color-switching mode, the transition from blue to red is perfect and gentle, but from red to blue, it just switches instantly. That is rather jarring. Two, and this is not a big deal, the "stars" are clearly projected on a grid. It's much less noticeable in a lower brightness, and it's not that annoying.Oh, also, don't look directly at the green laser that projects the stars.My favorite way to use it is on the first mode, where the colors don't change and are a mix of red and blue and purple. Movement/rotation on. Lowest brightness.Overall, I absolutely recommend it.Projector lights for rooms in houses and apartments are now very popular. The BRSTAR Northern Lights Projector is easy to use and is easy to use. You can change the colors, make the clouds move and you can brighten or dim the lights. This would be a great present for a child or any family member. It is very relaxing to just relax under the stars while drifting off to sleep or just enjoying a quiet evening at home.Easy to use - 5 stars is my rating. It would make a great Christmas gift or birthday gift.This light projector is very cool. It is easy to use and has different options of brightness, light color and patterns. It's a great night light or light when you don't want to turn on your lights. Kids love it a lot.
