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!!

The media could not be loaded. This speaker is way cool! It also picks up voices and sounds from the room if there’s no music playing. Really fun and neat product. Was a hit for Father’s Day.

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."

This is a nice desktop device that does work fairly well. However the fluid does start to separate after a bit. Still okay for the price and novelty.

Love it. Fast delivery and get product.

The media could not be loaded. Worked well for a week or so, but now there is a brown air bubble that has separated and it completely ruins the aesthetic. I only used the device a handful of times before this happened.Seems to be an issue for others, so I would buy with caution. For $129, I expect better.Amazon is saying I cannot return it, so I am hoping this review finds its way to the company. Would happily update the review if they can help.

This is really fun product to set up on the side of her room whenever dancing and romping around. It picks up sound very well and dances quite like it says. I am a little disappointed that it's not a speaker in of itself. I think if they added a speaker to it, it would really bring the whole thing together.

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.
