Produto Barato, mas a qualidade não é a melhor.

Great decoration in the apartment. Looks good and works even better. My friend had a gift of great joy. Purchase this toy definitely recommend it.

Legal como peso de papel. Perde o embalo muito rapido, não gostei desta parte. Metal somente as bolas todo o resto feito de plastico.

it's a small piece but it's working like it is intended. You can tell visually to children some of the science of nature.

Consist of metal balls, has a good design, works like it should do in a chain reaction. The balls are hanging in a plastic frame which looks metal on picture. Movement stops after 15 seconds, should last longer. It would be great if it lasted longer, the balls stop too fast after the first push....

Movement stops after 15 seconds, should last longer. It would be great if it lasted longer, the balls stop too fast after the first push. Also I would like real metal frames, since that will increase the quality and look and feel of this product. As far as I got this it is a nice thing to have. Everyone coming into the office touches this thing, because everyone knows this thing from movies. Read more

It's cheap for a decoration toy that can be used when teaching kids. The balls are small and light, so they lose inertia rather quickly. This results in the cinnetic movement stopping after a few moments. If you want it to keep moving; just pick the metal balls every now and then. It's a nice gift for friends who teach! It does work, but I'll buy a larger one with all steel and wood construction for myself. It's a nice decoration toy and it makes people wanna try it. Read more

Everything works perfectly and it makes my desk more beautiful. Except the balls, all of the rest items are made by plastic. And when I received the delivery, the item has been broken a little bit. But it's quite ok because it's hard to see the broken points. But I'm not sure it's still ok after falling down from the desk (if you have a child) Nice item with reasonable price You should by it for decorating your desk or relieving strees Read more

It works. It took about a minute to assemble and start testing the laws of physics. Fun little thing (emphasis on little, see below) and good looking. The balls themselves are quite small, consequently they lose inertia quickly. Outside of the metal on the balls, everything is made of plastic...... It works. It took about a minute to assemble and start testing the laws of physics. Fun little thing (emphasis on little, see below) and good looking. The balls themselves are quite small, consequently they lose inertia quickly. Outside of the metal on the balls, everything is made of plastic... including the base and arches that support the hanging balls. Take care of everthing turn a mess For the price, you won't be upset by the size. This is a fun little desk topper that people love to toy with when they stop by. Beaultful and nice Read more

Apparel is nice for what you pay for it. Looks great on a desk of someone who claims himself to be a great thinker. Nice toy to show off. The bottom is plastic but still has a quality look.

Looks great on a desk of someone who claims himself to be a great thinker. Nice toy to show off. The bottom is plastic but still has a quality look. Works for a very short periode of time. Not more then 30 seconds. Full plastic. All balls move when used. Not really calming just fun to watch it work and try to understand why it stops so fast. If you like desk toys great item to have. If you want if for the functionality buy a better one. Read more
