It was a gift for my grandson, and it was all tangled up - plus missing a few balls! I didn't want the hassle of returning it - I'll just look around for better quality one. Sorry, but it was a disappointment.

Super fast delivery! As pictured. This is a small version and made of plastic. Not super fancy, but what I expected from the description. It was for my 10 year old and he loves it.

Really neat desk toy. The kids love it at work, but one of my autistic kids got ahold of it and got it so tangled we had to get a new one. Fun to watch when you're bored and just in general.

It is well described in the e-catalogue as far as its dimensions but I was disappointed after actually seeing it, it looks and feel small and flimsy. The ones I have seen in the past were better size ( about 8 inches rather than the 4.5 inches).

My grandson saw this toy on my desk and like the way the balls were moving back and forth, he ask if he could have it so I gave it to him, now he can play with it when ever he wants to.

  Not the greatest quality, very small,
Posted By:
1 people found this review helpful

The dimensions of this toy were probably listed, I don't recall, but it is far smaller than I expected. I had one of these as a kid and, like most things recalled 25 years after the fact, it was better than the stuff today. There were Newton's cradles cheaper than this one, but with the higher price and ratings, I chose this one. I shouldn't have bothered. It might be ok for a grown up, but even an older kid will mess it up ASAP. If you really want one of these, go with a more expensive, nicer one.

  Okay for the price,
Posted By:
1 people found this review helpful

I have seen versions of this kinetic device on numerous occasions and after finding this one on Amazon, based on the price, I decided to get one. It's okay but not near the quality of the ones I have seen in the past. I probably should have spent more and gotten a better one but then again: It's okay for the price. If you simply want to demonstrate kinetic motion, buy it. If you want one where the motion continues for a while, look for one with a higher price. The seller did do a good job of packaging and shipment.

Very cheaply made toy, following irections, we swung one ball to start, only runs for a few seconds, (no kinetic energy demonstrated). Will donate to Goodwil and let a child have it.

The one is quite good. But it would be great if you could change the buffers to other material because they are somewhat annoying.

  Great item but do not let "gut wire" get tangled!,
Posted By:

A very nice size for this product. Shows off the"Action, reaction idea", but if the gut wire becomes tangled the unit will not work as well once the tangle has been straightened since the 'kinks' in the wire change the true length.

  Oscillations don't last long,

Smaller than expected, the oscillations don't last very long. Probably light weight balls and thin strings might be the reason

  fun, but smaller in size than I expected,
Posted By:
1 people found this review helpful

The product is cheap and fun, so it's perfect for a small present basically to everyone. Drawbacks - ( I didn't pay enough attention when ordered it) the device is small in size, pendulums are short and therefore the frequency of oscillations is very high). Another thing - the strings are often get tangled, (again, I wasn't careful enough) once I spent half an hour trying to untangle them, and then my girlfriend stepped in...

  It's ok,

Kinetic Motion Desk Toy on gave him for Christmas and my friend like ... but I believe that the movement is not maintained as it should be, I think some balls do not conform exactly to keep moving for longer. One was a Christmas present.

  Small and easily tangled,
Posted By:

I purchased several kinetic sculptures for my 2 year old son. This one is in a tangled up mess on my desk. It's metal balls, with a plastic frame and thin fishing line for the string, which gets tangled up easily... Its easier to cut the strings and restring it ever time it happens. I should have bought a larger one of better quality.

  Fun and nerdy,
Posted By:

The toy itself feels a little shabby, and I use it more as a nerdy desk decoration than a toy. I bought it for a frien who is a high school physics teacher and it serves as a good demo, although the size may be slightly small if you have a large classroom. The base is plastic and the two scaffolds feel a little shabby so don't let young kids play with it. The middle balls start to move as well when you pull the outer ball far enough and that technically is not supposed to happen. But as a nerdy decoration I love it.

  It broke...multiple times.,
Posted By:
1 people found this review helpful

First off, I should have known that, for the price I paid, I shouldn't have expected much. The whole thing is made of plastic and fishing line. The slightest fall tangles the strings beyond repair. I fixed it once, and the second time, the string on one ball broke. It lasted about 2 weeks before I had to throw it away. Just goes to show that you get what you pay for.

This particular model has to have the bars placed into the base and it takes a good push to seat them. Unfortunately a good push is also all it took to break it. Even after that was fixed, the balls hardly click at all, about 5 times, before the lose too much energy and stop.

Good office gift. However, looks better in picture, after receiving does have an inexpensive look. Would have been better with a wooden base, instead of plastic. However, it is still a good office desk gift.
