Question: Does it autoshut off after a period of time or stay on until switch
Document: I am disgusted that this simple design doesn't remotely resemble the picture it's meant to. I HATE THIS! the colors don't change unless you switch it off then on, therefore it stays on one color the entire time its on. The plastic strings all go up and hardly bend down into a mushroom shape like they are supposed to. I am disgusted
I was sadly disappointed to find that the item shipped is not the item that was described - it does not have any sort of vibrating or rotating feature at all, just an on/off switch, and it does not change colors unless you turn the light off and then turn it back on.
ridiculous!!!! very noisy and rotates off the table. luckily i found a heavy small cup to place it inso now i am satisfied. construction is poor with tiny screw and switch on bottom, otherwise quite pretty.
Yes...It vibrates. But if you place it on carpet, no problem. However-  you can flip the switch the other direction....and it does not vibrate (duh) It changes through colors, not all 4 at once. It is slow and rhythmic. I am an OT and use this a lot with my kids. My own son has one in his room and lvoes it as well.
What arrived is not what was advertised! It did not rotate or vibrate at all. There is a spot where a switch should have been-- maybe that was the rotating part? Many of the fiber optic pieces started falling out within 5 minutes of opening. I have one that works correctly, but not from this seller. The one that works is really cool, but this is a piece of junk. Don't waste your money!
I can't figure out what other reviewers are talking about---mine not only doesn't rotate or vibrate, there isn't even any option for it to do so. It is a tiny red plastic cone with fibers coming out. Yes, it's pretty and changes colors, but there is nothing but a tiny on/off switch on the bottom. No rotation at all and doesn't flair out anywhere near as much as the picture. The picture looks much bigger than it really is.
I realize it's very inexpensive but this thing is beyond bad, it will light up after you stuff 3 batteries in it but mine absolutely refuses to rotate, when you switch it over to that it vibrates so badly it'll &#34;walk&#34; off the table... but it won't turn. I know you get what you pay for but this is stupid, not worth one red cent. Whatever you do don't buy one, it's junk.
I ordered two of these because it sounded like a great deal. Should have known based on the price... both lights came, and neither worked. There was a place for an "on/off" switch, but it was MIA. I put batteries in BOTH of the lights, one of them did not work at all, and the other one worked for 5 seconds then turned off. I am returning both of them for a refund. I highly reccommend NOT purchasing this product! !
It may be the spinning mechanism, but it vibrates while doing this. I thought I would find that annoying, but while it does that, all the fibers make a small circle pattern on the end making it MUCH more interesting to look at. My daughter LOVES this setting, can switch it on, and run her hands through the fibers, making them do cool things while they light up. Definitely worth the couple extra dollars to get more than one color!!!
I bought this item thinking it would give my husband, who is in a nursing home, the same pleasure he always got from watching the ever-changing lights on our fiber optic Christmas tree. It doesn't live up to the photograph. The housing is flimsy, the on-off switch is difficult to get to, and the colors are pale and insipid. It arrived about ten days ago and I haven't decided if I'll even take it to him.
Answer: yes
