Frekvens-Magnetic Fluid Pickup, Venom Music Rhythm Light, Visualized Desktop, Trendy Ornament, Dance Liquid with Music, Gift Toy

The product works better than expected.

When i received it, it had a bubble that disappeared after a day.

It can be connected to the speakers, can capture the ambient sound as well as work by itself without being affected by external sound.

This unique and visually captivating desktop ornament offers a mesmerizing experience. However, mine has a small air bubble that has trapped some of the ferrofluid. Despite my attempts to clear it using the magnet, the issue persists, and reducing the amount of ferrofluid in the bubble only exacerbates the problem by giving it a brownish appearance. Based on images and videos of similar ornaments, it seems that this air bubble is not a common occurrence. Unfortunately, this imperfection appears to be permanent. While it is somewhat distracting, it does not significantly impact the overall experience though the trapped ferrofluid remains a static element rather than interacting dynamically with the rest of the liquid. Never the less i would recommend this to anyone as a great captivating almost relaxing gift.
