Question: I just opened the strobe light and the ball does not rotate or spin.  Is this a defect or can I do something to make it spin?
Document: so far it works great i was suprised that the light s were rainbow so those of you wjho want the traditional white shimmery lights and not the rainbow lights i suggest you look else wear love it other than that little suprise also its able to hang up not just sit on a table or floor or something so im pretty pleased about that as well will make a great gift for my nieces sweet 16
Both lights were broken off, mirrored ball was broken off, both beyond repair. One blue light on base was smashed in also. It looked scuffed like someone had dropped it and then repackaged it all broken on purpose. I did return it for a full refund, but of course had to scramble for something else... a $40 rental to use for party. Very disappointed.
I liked using the strobe although it didn't shine a brightly as I thought it would. I would probably not purchase this particular strobe light again but would purchase a larger one.
Though it was smaller than expected, the little ball reflects off the walls enough to keep the party moving! It rotates and was we were able to mount it on stand with the other strobe lights
This is a good product. Gives off good light in a dark small room. It does not make any noise. It adds great effect. It can be hung from the ceiling or set on a table. Very good for Disco Themed parties.
We wanted to get something to spice up our play room a bit; the kids love dancing to their music anyway, but having a disco ball brought it to the next level! Color us happy :)
Is really small I speck something  bigger. Looks like a toy.
This item was a huge disappointment. My granddaughter had asked for a disco ball for Christmas and this one did not work at all. It would not even turn on. So far my granddaughter still does not have a Christmas gift from me as I have not been able to locate another one I like. Hopefully I can find one that at least has a light!
My girls asked for a disco ball for Christmas, and this item exceeded my expectations (so far). I love the fact that it is portable. The light effects are really good. My 6 & 8 year olds were fighting over who would use it as a nightlight. During the day, they blast music & have "dance parties". It's really cute.
I am a true Disco-ite! So this disco ball made my day. I use it when I do my x-box dance games and it gets me totally in the zone. I love the colors of the lights. I am 53 years old but this light brings me back to my younger years when I went disco dancing.
Answer: yes
