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.

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!!

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

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

Era para un regalo y le encantó, toma muy bien los sonidos (hasta cuando se habla) es hermoso verlo con musica

Mesmerizingly cool
