Great value

Lost the original magnet and this one performs just as well. Nice that it comes with an LED at its price point.

Led light and magnet

Nice product but I have difficulty affixing to my bottle. Any suggestions on placement would be welcomed.

Casey Hoffman
Great addition to my desk

Fun and ambitious desk deco which offers a nice interactive sciency vibe. I'd give 5 stars had I not purchased the LED light addition. The LED quality is lacking for what should be presented as a technical desk adornment. I'd suggest looking into a high CRI emitter in a neutral tint as to not impact the color and tone of the Ferro fluid; nichia 219b emitters are top of the line and would really make the display pop.
