sovenomund Dancing Ferrofluid with Music Rhythm, Ferrofluid Speaker Music Mate, Symbiote in a Bottle, Ferrofluid Display Lamp, Desktop Decor, Teenager Gifts (Not A Speaker) (Does Not Make Sound)

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!!

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.

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.

It's attractive and worked nicely for almost 24hrs. However, this one leaks whatever the clear fluid is! From the rapidly appearing crystals it appears salt like. It arrived in an undamaged package but the leaking may have caused it to malfunction. It no longer works.

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!

Updated Review: Below is my original review, but I’d like to update it. Since posting, the seller contacted me and offered me the choice of either a refund or a replacement. I chose the replacement because I truly think this product is awesome. The seller not only sent me a replacement but also insisted that I keep the original defective product. Even though it has a flaw, the original is still quite usable. I really appreciate the seller’s dedication to excellent customer service, and I applaud their efforts to make things right. Thank you! Also have a defective piece. Just my luck it has the brown oily particle which I believe was the ferrofluid that got decomposed. Due to that parts floating nature it covers the top opening which messes with how the non defective fluid reacts to external sound. Please customer support can you contact me for a replacement I’ll gladly send this one back.

Keep in mind, this is NOT a speaker. The listing DOES say it's not a speaker somewhere too. But anyway, I've tried tons of audio visualizers over the years, and it just seems like nothing really goes with the music. At least, no so that you can really tell it does. Some kind of go with the music, but nothing compares to how well this ferrofluid goes with it. You can use the magnet it comes with to play with it while it's turned off, but the real magic happens when it's turned on and close enough to an audio source. Which brings to mind the only real downside, in my opinion. To detect the audio that makes the ferrofluid move, there's a mic on the back. And while it still detects audio pretty well, at this price point it would be nice if it had the ability to increase and decrease the mic's sensitivity. Other than that, it comes with a cord with a regular USB-A connection on one side and a USB-C connection on the other side. No little power brick that plugs into the wall, but that's pretty standard these days. Also, the cord isn't something that's just to provide power that needs to be plugged in all of the time. No, it's actually for recharging this device, which means it CAN be operated wirelessly. And one more thing. If you order this and it comes with a big ugly air bubble in it, just put in for a replacement and it should be replaced with no problem. Sure, it's aggravating to have to do that, but I promise it's worth it. I just wish Amazon would quit putting their stickers on the actual product boxes of everything they ship, that has the kind of adhesive on it that can only be described as, "Evil."

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

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