Lots of fun for kids and adults


The guys at nanodots sent me over three of their 216 piece kits with silver, original, and black colors. The little dots are all the same minus the color of the little balls. The original color costs $29.99 for a set, the black version is $34.99, and the silver version is $34.99 as well. Each kit has five extra nanodots, a carry pouch, and an instruction page to tech you some tricks.

In Use

The delivery guy happened to drop these nanodots off at my house on a Friday when half the neighborhood was here playing with my kids. I popped the box open and took the nanodots out and as soon as the kids saw them, the house was filled with shots of "awesome" and "cool" followed closely by "can I play" and "give me some of those." These little balls are small, but the magnetic attraction that they have is very strong. You have to pull surprisingly hard to get the little dots to come apart.

That means that when you use the nanodots to build something the device nanodots are strong enough to keep their shape. My kids built all sorts of things like necklaces, bracelets, and more. These things have such strong magnetic attraction, you will want to keep them away from computers or anything else that uses magnetic storage or you risk harming your hardware.

We spent hours playing with the nanodots without a complaint one from the kids other than asking if Santa will bring more nanodots at Christmas time. If you buy these things go ahead and get several sets, you will like them. The original nickel color and the silver color are almost identical in shade. It's hard to tell them apart when they are in a big jumble. The silver dots are slightly shinier than the original.

Other than the risk of harming your electronics if someone sticks these things to your iPhone or notebook, the only other thing that you have to get used to is the tendency of the strong magnets to attract to each other even if you want them to stay apart. My son happens to be learning about magnetism in school right now so he got a big kick out of the fact that some of the nanodots would repel each other rather than attract depending on what side you were trying to connect together.

I would have never though a bunch of magnetic BB's would be so cool. Of all the stuff I have reviewed over the years, the nanodots are certainly right up there with some of my favorite gear ever. These are well worth the money and tons of fun.



  • Huge fun for the whole family
  • Super strong magnets
  • Hold shapes very well


  • Building can be tricky, especially for younger kids
  • Small balls can be a choking hazard
  • Can damage electronics with magnetic storage


If you want a fun building toy that everyone in the family can play with and have fun, nanodots is the building system for you. These things are awesome!
