I have one of those. They're awesome. The one I have comes with these things you can magnetize on to the disc. Then when you point a laser at the disc while it spins, it reflects the light onto the mirror. It apparently looks really cool.

Oh that’s what those triangular magnet things are. I put them in the drawer for now to so that I wouldn’t lose them. I’ve noticed too that as it spins, sometimes it clicks and clacks against the base. Does that mean the base needs to be cleaned or is it just off-balance or what does that mean?

It may be both. Make sure it's balanced and not wobbly. And yes, those triangle things reflect lights

OK, I have the base sitting on a level surface, and since I don’t know where our glass cleaner is I just wipe it off with my pad that came with my cell phone so that way I don’t have to like worry about scraping or scratching against the base with those rough cloths

That's fine honestly. I did notice that in your demonstration, it did click here and there while spinning. I wonder if mine does that too. Hmm.

Yeah, I have heard some discs do that and some do it more than others. I was just wondering if maybe there was something that caused that like loss of balance or a little bit of friction on the base, I’m not sure which. I’ve actually heard of those that have metal bases too. But those would probably sound really weird

Not sure. Now I gotta find mine, and give it a spin to see.
