BlastCase Newton's Cradle Art in Motion, 7 1/4-Inch Balance Balls - Black Wooden Base

This was bumped up from average because of its popularity with my children; it was a Christmas present for them. On the down side, when swung around, the balls get tangled up, and it can be difficult to untangle them. Additionally, the alignment seems slightly off, and the perpetual motion stops in less than a minute.The collision with the clacking sound keeps the kids entertained, almost mesmerized by it. At least until they start fighting over who is going to swing them. It's a decent size, and the base is stable enough to hold it in place, plus it's sturdy enough to handle small children fighting over it. the base is a heavy wood particulate, the bars and balls steel, and the lines are a filament like fishing line, welded between into the bar and balls. To assemble it, you just slide the bar ends into the holes in the base, just make sure they're fully seated.

From time to time it would get tangled up but I sure do like the motion

When I took it out of the box one of the strings was detached from the silver plastic bar. You could tell it was really cheap packaging and the structure itself seemed pretty cheap as well, all plastic with just some fish line suspending the metal balls. Also the broken string was on the ball second from the right, so it kind of disabled the whole thing and I couldn't reattach it with superglue and I ended up throwing it out. I think if the packaging had been given a bit more thought and care the line might not have broken. Otherwise I'm sure the actual device would have been fine, just disappointing because I was so excited to get it only for it to be broken before I could use it.

This is the most awesome toy. I can play with it for hours at a time. It also helps me calm down when I get upset. My doctor recommended it along with some fidget toys so I stop picking at my fingers. Anyway, I found that if you get too carried away the strings can become tangled. So be careful. It's best to just play with it on your bed and not carry it around.Warning, the soft clicking of the metal balls irritates some people when they watch TV. The noise doesn't bother me at all but my si-fi friends, Randy and Kyle get all upset every time I pull this out during our Battlestar Galactica marathons.

Product was completely destroyed and unsalvageable upon arrival; though that is not why I deducted 2 stars. The "string" is very thin (brittle, almost) nylon and is very easy to break by just slightly pulling with your fingers. The base is plastic (as stated in the product description) and is not very heavy at all.

This cradle appears sturdy and well built, with nice heavy balls, but the cradle only operates for about 5 seconds (or less) before the balls get out of sync and the effect stops. Not sure why but I know that I've seen other Newton Cradles that run for a much longer time. This particular model uses fishing line to suspend the balls.

This item was at the top of my 10-yr-old son's Christmas list. He really enjoyed having it the first few days after the holiday, but the fish line that holds the individual metal balls became very tangled and 4 of the 5 balls could not be separated. He was very disappointed, as we had to throw it out. It was fun while it lasted!

It is what it looks like, a Newtons Cradle. I would not pay twenty dollars for this with my own money, but I would love it as a gift! The rods fall off sometimes but it's easy to assemble back.

It was a good size wooden 7" base (not plastic). The strings were not tangled at all (not like others I read). It was neatly packaged in a box with the strings and metal balls neatly separated. It was easy to assemble by placing each pole in the 4 holes in each corner of base then it was ready to use. The metal balls are nice and shiny. No rust. No tangled strings. Large wooden 7" base (not plastic). I always wanted one. Good price. Good quality. Good purchase!

Great item at a great price and top service . Son is delighted with his new gadget !

DO NOT BUY THIS PRODUCT!!!i bought it, and 2 hours later decided to cancel the order and they wouldnt do it! this is horrible quality, its nothing like it even looks like in the picture. it is cheap, faulty craftsmanship, and looks like it cost $0.50.Piece of s*** just like the seller

It is exactly what I wanted and it is a good quality. Thank you.

Decisamente non è un granché non vale il prezzo pagato il dondolio dura pochissimo al massimo per esagerare 20 secondi, non lo ricomprerei di certo.
