Dancing Ferrofluid Sound Visualizer, Mysterious Liquid Office desk Decor | Ferro Fluid Music Visualizer, Type-C Charging, 8H Play Time, Office Relaxing & Gift for Teens

I bought one of each of the wood colored and the gray colored Ferrofluid Music Mate. There is a lot to love about these little magic dancing boxes. Both of them look great and the overall workmanship is really good. I bought them as gifts for my two teenage boys, and they both really loved them. For those looking to buy one, I will outline the things that I really enjoyed about it, and some minor things to be aware of. I really liked that it is not a speaker. (I have plenty of those) It has a very sensitive microphone that controls the action of the ferrofluid. Even talking in the same room will create motion in the fluid. The louder and more consistent sound will keep it in the center. When it is quiet, the ferro fluid often drops out of the center. This is fine and adds to the motion. The back of the round glass is white and lights up when the unit is on. It is reasonably bright and really accents the ferrofluid. I thought the jewel in the corner would light up, but it does not. There is a really bright blue led on the back to indicate power, but it can be covered if needed. As a bonus, it comes with a really strong small magnet attached to a holder that looks like a chess pawn. It is really fun to move the fluid around and interact with it. One unit's magnet was actually two smaller magnets and could be split apart. This might not be great for little kids, but I don't have that worry. I don't remember if this was common to both units. The magnets work regardless if the unit is powered on not. When you get it, it is normal to have some extra non-ferrofluid oil in the unit (looks like a floating light brown bubble). Both mine had this. If you set the unit on it's side the oil will be prominently displayed at the top edge of the glass, which doesn't look great. If you place the unit vertically as shown in the pictures here, there is a small indent behind the edge of the wood that traps and hides that oil. My older son had wanted it to sit under the monitor, but it really needs to be in the normal vertical orientation to look right. My kids leave them plugged in, but they do have a battery so they will run on their own. I have not tested this much, but they ran for at least a few hours on Christmas before we plugged them in. If you are looking for an awesome desk gadget, a replacement for your lava lamp that is long gone, or a really neat toy that is brimming with science, this is a perfect gift for you.

This thing is super fun. I keep it on my desk and talk to it to make it dance when I’m bored. I let it charge overnight and then during the workday it runs on battery all day no problem (~9 hours generally). I turn it away a lot so that people who come into my office are greeted by it and it’s been a big hit. People love it and it’s even diffused some stressful situations. Great conversation starter. The ferrofluid itself is very reactive to the magnets and when it really gets going, it likes to split apart into smaller forms and then reform later. It’s a ton of fun to watch. One caveat to all of this: the first one I ordered had a manufacturing defect (dark line across the width of the white backing circle) and suboptimal ferrofluid reactivity. I exchanged it and the replacement was perfect, so no harm no foul.

These are absolutely awesome and give a feeling of wonder to everyone who sees them! I have had my own for about 2 years now and gave one as a gift to my partner about a year ago. We both keep them in our offices, so we get constant compliments and inspire curiosity and joy as people watch it respond, move, dance to voices and music. It honestly looks just how it does in videos of it -- super cool and a little out of this world! I love seeing it even after two years and it works beautifully, was easy to setup, and remains just as responsive, clean (the glass is clear), and interesting to this day!!

Worked great for the first few months. And then it sat on our shelf for many months without use. Today (only 9 months after purchase), I noticed a new bubble inside the water filled with a weird brown oily substance. The fact that this happened less than a year into ownership says a lot about this product. I expected far better quality for this much money.

Saw this on a YouTube channel and bought immediately for my musician boyfriend! He loves it and we both agree that its hypnotic and fun to watch dancing around. Had to knock off a star because it’s wildly expensive for what it is however we still enjoy it!

My son wanted a ferrofluid bottle for Christmas and I didn't think it was that big a deal. He let me know right before Christmas that was one of the things he really wanted. So I ordered a cheap $30 ferrofluid bottle. But then I saw this and thought, "Maybe this will be cool too." Boy was I right!! He LOVES this gift and while it wasn't super cheap, it was by far and away his most appreciated gift and I felt really good about it because it showed I was listening and I went above and beyond what he had asked for. That said, how well does it work. It is pretty solid. You aren't going to get wild, bottle filling gyrations, but it does dance with music or talk. It responds very well to lower frequencies. And it is very neat that it has a battery, so when you unplug it and haul it around, you don't have to plug it in again to get it to work. This is a really clever design, would be great for a science teacher, and for any science minded person who "has everything."

Totally random purchase. I was a little worried cause most reviews were good but a few had particularly bad experiences (seems like factory issues and product defects), including the glass breaking and oil/ferrofluid spilling onto their desks. But, I’m glad I splurged for it. Playing with the magnet manually is a lot of fun, did that right out of the box, though I’m a little concerned banging the metal magnet on the glass a lot might not be great haha (probably can put some cloth or rubber at the end of the magnet cause it’s strong enough still). But, when you get it plugged in and turned on, the backlight is BRIGHT, and staring it react to music is a lot of fun. I had sort of imagined it like those videos where people put sand or fluid on speakers and it makes very cool, perfectly parallel shapes. It won’t make and hold specific geometric shapes with music, it’s sort of like lava lamp but fast moving (globules bounce up and down, breaking apart and coming together), though in that random bouncing you do get moments where those signature Ferrofluid sharp spikey arms pop out. Behaved differently than expected but, I find it equally awesome and mesmerizing. The wood is nice looking too. Mine did have a TINY air bubble you can see when it is rotated but when it sits on a desk as intended, that bubble disappears into a tiny little gap at the very top of the circle and seems to cause no issues.

I haven't tried the product but I bought it as a gift thinking it was a speaker since its designed to look like one according to the picture and is advertised as a "speaker". I figured for the price it would contain something that produces sound. It looks like an old fashioned radio which suggested that it played music. It has no such speaker. I told the person I was giving it to that it was a cool sound device that dances. When opening the package, because we don't open gifts here before giving them, I discovered there was no speaker function and looked like an idiot. I had to read the instructions, which should be available online, because thats the only place it says "DOES NOT ACTUALLY HAVE SPEAKERS.". This frustrated me and sort of ruined the gift giving because this person didn't get gifts for their birthday. Now, why would you put speaker and ferrofluid speaker in the title and then put THERE IS NO SPEAKER in the instructions? Now, this might be a design flaw because I know the guy who writes documents and the guy engineering it probably don't talk -- but to Americans this appears to be dishonest. FERROFLUID SPEAKER MEANS IT SHOULD PRODUCE SOUND. FERROFLUID. SPEAKER. FERROFLUID SPEAKER. "Music mate" isn't a thing other than suggesting its "together with music". "Mate" doesn't suggest it loves music and therefore dance together. Ferrofluid Speaker Music Mate suggests its a speaker with or made of ferrofluid that is apart of music. Anyways just thought I'd help with the language barrier. Anyways, I'm sure its a 4/5 but this seriously messed up an already bad day. It haven't had more than 2-4 hours of sleep for about 11 months now and thats just 1 of 100 problems I have.

Molto divertente

It tottally lives up to the expectations, has a powerful sensor that makes the bubble dance to anything, even normal human conversations and sounds. It's a great accessory to your desk or in a living room next to the sound system.

Works but not as I expected, looks nice, but not worth the money.

Great fun and a well received gift..... not over sure about value for money, but that's the choice for the individual

buena calidad de materiales sirve mejor con musica movida, con clasica casi no se mueve
