Overpriced- Plastic- not good quality

$16 is a high price to pay for this. The parts are plastic, the balls are metal. This is obviously not a young kid toy. My 13 year old son wanted this for his birthday- which he could have handled caring for at his age. He had just opened the package and when we weren't looking my 4 year old played with it. In a matter of 1 minute all the balls were tangled and one broke from the string. I think the value of this is more like $4. If you buy this- and you don't want it broken by kids- keep it up high at all times. We learned our lesson.

Very soothing!

We love this! This is very soothing when you're trying to fall asleep. The rhythmic clickety clack is perfect for relaxing to. It's also meditative to play with and watch - our whole family loves it. It is also really well made, very sleek looking, while also being light. It's a great buy for the price -- no need to get any more expensive version.

Cheap, junk.

Terrible, junk. Would return this in a heartbeat if I could. Made out of cheap plastic. Didn’t even last two weeks.

Newton’s cradle

Easy to assemble, but kind of cheap feeling for the price.

Cheap plastic

It's plastic and kind of cheap. Balls are not alligned properly and once I start one they get all out of order.

Very flimsy

All lines knot up to easily when used, very cheaply made

Don’t buy

Totally junk. Balls don’t swing, get twisted. Cheap plastic.
