So I was BLOWN AWAY at how quickly this arrived more than anything, I think it literally came the next business day (ordered Thurs evening, so Friday for all intents and purposes, and was on my porch Sat. morning! WOW!) and I don't even have Prime right now! Dang... Now to the product. My daughter and I plugged it in and both went "WOAH! Cool!" because this thing is really cool. It has on and off, a button to control whether the nebula and stars move or not (or just the nebula moves) and a button to control the brightness, but honestly "full tilt" is the only way to run this thing. You can have both, just the lazer (stars) or just the nebula (blue haze) and the nebula feature is really far out. Looks like an enchanted spirit portal or some kind of temporal anomaly wormhole thing on my ceiling which is EXACTLY what I wanted. Kinda wish I had one of these in my teens and early 20s now, would have made certain "spiritual journeys" I took really cool *wink wink*. A MUST for those who like to veg out to music with "atmosphere" or anyone into lava lamps and chill vibes. I'm thinking a psychedelic or Jam band would really get some use out of a pair of these things as stage lighting combined with a fog machine, or if you are into peaceful nature music and meditation this will totally "up your zen"....Now...If there is ONE Drawback or Negative, it would only be that there sadly aren't more colors or pattern combinations on the unit. This thing is kind of a "one trick pony" to be honest, but... the one trick it does do it does reaaally 'effin well, and that is to create a trippy ethereal ambiance to compliment any dark space. You can put it close to a wall and get a relatively confined effect but it works best from a corner aimed at an opposing wall or best yet, the ceiling. Super happy with this little guy and I do hope it is a quality item that lasts a while because I am super stoked about having this. (P.S. It drove my cat NUTS and he kind of freaked out...lol)5-stars, the photo's DO NOT LIE. Buy with confidence. I will update if the thing dies unexpectedly but for now I am a big fan and will recommend with confidence! Super Trippy!NOTE: asked me to rate the "remote control" on this item... I did not receive one. Not that I really need it, but was it supposed to come with one? Meh... let me know! I dont really care or need one, but Im curious.
