SovenomundFerrofluid Speaker & Indicator Lamp, Dancing with Music Rhythm, Desktop Decoration, Teenager Gifts (Imitation Bamboo Pattern)

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

Disappointing quality at that price, the fluid had already separated on arrival so leaves this cruddy bit of residue that never joins the rest.

Pretty pathetic. The neutral position has the ink sitting at the bottom of the glass enclosure, not in the middle as pictured. It bounces around a bit in response to sound but it looks pretty crap.

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.

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

This is really quite an incredible item. I was skeptical when ordering it but to be honest it does the job : everyone is amazed by how it works, worth the value. If you want to make a good gift to someone passionate about science, you can def go for it !

Mon fils ne le quitte plus . ArticleDe très bonne qualité. Génial avec de la musique .
