5 Large Beads Newton's Cradle Balance Balls Desk Toys Office Decorations with Black Wooden Base Desk Balance Balls Fun Science Physics Toys for Office/Bedroom/Living Room

Very well packaged and a nice larger size cradle....definitely worth the price.I bought it for my 5 yr old daughter who has adhd....it really helps her calm down when over stimulated...she calls it her timer 😆.

Good quality, heavy duty, and it arrived in one day! The packaging was excellent, keeping the balls from getting tangled. I purchased because I am teaching a church lesson on opposition and what better than Newton's 3rd law of motion to demonstrate that.

i got this for my 9 year old daughter for Christmas. she liked it, but they get tangled easier than i thought they would. the strings are thin, and the size is smaller than i thought. but, to the positive parts, its light and the balls never seem lose or fall out. its easy to pull back and we've never had a problem, (other than my 2 year old trying to tangle it, but thats my problem.) and it never gets annoying with the sound. 4 stars

We love this. For safety, I used a nail file to smooth a few sharp wires at the top. Otherwise, perfect!

Movement is very smooth and precise, no need to build,it comes ready right out the box,great gift,keeps you entertained for hours,functions very well showing the laws of physics and inertia,very durable.

I recently purchased the SEVNPRIME 5 Large Beads Newton's Cradle Balance Balls as a desk toy for my office, and I have mixed feelings about it. Here's a breakdown of my experience:Pros:Kinda Fun: This Newton's Cradle is a delightful way to pass the time. Watching the balls swing back and forth is oddly satisfying and can be a great little distraction during breaks.Affordable: Priced reasonably, it's a decent pick for someone who wants a desk toy without spending too much.Cons:Build Quality: The term "you get what you pay for" rings true here. The build quality is just okay, not exceptional. It feels a bit cheap and I'm not sure how long it will last with regular use.Performance: While it works as expected, the momentum and movement of the balls aren't as smooth or lasting as I hoped. It's good for a short play, but don't expect mesmerizing, perpetual motion.Overall: If you're looking for a budget-friendly desk toy to add a bit of fun to your workspace, the SEVNPRIME Newton's Cradle is a decent choice. Just keep your expectations in check regarding its build quality and performance. It's a classic concept packaged in an affordable but somewhat underwhelming build.

Arrived in perfect condition and it is just what I was looking for.

This is a fun item to have at home or work desk. Rarely can anyone pass it without playing with it. My husband took it to work but didn’t use all the original packaging and it fell off car seat to a tangled mess. Good thing I do those tangled puzzle strings on my phone since I was miraculously able to untangle it. Lol
