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

Great fun and a well received gift..... not over sure about value for money, but that's the choice for the individual

Molto divertente

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 !

Sieht Fantastisch aus. Wird fast jeden Abend eingeschaltet.

I bought one of each of the wood colored and the gray colored Ferrofluid Music Mate. There is a lot to love about these little magic dancing boxes. Both of them look great and the overall workmanship is really good. I bought them as gifts for my two teenage boys, and they both really loved them. For those looking to buy one, I will outline the things that I really enjoyed about it, and some minor things to be aware of. I really liked that it is not a speaker. (I have plenty of those) It has a very sensitive microphone that controls the action of the ferrofluid. Even talking in the same room will create motion in the fluid. The louder and more consistent sound will keep it in the center. When it is quiet, the ferro fluid often drops out of the center. This is fine and adds to the motion. The back of the round glass is white and lights up when the unit is on. It is reasonably bright and really accents the ferrofluid. I thought the jewel in the corner would light up, but it does not. There is a really bright blue led on the back to indicate power, but it can be covered if needed. As a bonus, it comes with a really strong small magnet attached to a holder that looks like a chess pawn. It is really fun to move the fluid around and interact with it. One unit's magnet was actually two smaller magnets and could be split apart. This might not be great for little kids, but I don't have that worry. I don't remember if this was common to both units. The magnets work regardless if the unit is powered on not. When you get it, it is normal to have some extra non-ferrofluid oil in the unit (looks like a floating light brown bubble). Both mine had this. If you set the unit on it's side the oil will be prominently displayed at the top edge of the glass, which doesn't look great. If you place the unit vertically as shown in the pictures here, there is a small indent behind the edge of the wood that traps and hides that oil. My older son had wanted it to sit under the monitor, but it really needs to be in the normal vertical orientation to look right. My kids leave them plugged in, but they do have a battery so they will run on their own. I have not tested this much, but they ran for at least a few hours on Christmas before we plugged them in. If you are looking for an awesome desk gadget, a replacement for your lava lamp that is long gone, or a really neat toy that is brimming with science, this is a perfect gift for you.

A bien fonctionné pendant un mois puis le ferrofluide s'est séparé en deux et une partie flotte comme si elle contenait de l'air. Impossible de faire une réclamation sur Amazon après 1 mois donc.... Pour le prix, le produit n'est pas de très bonne qualité.
