Better than expected
My first thought was that they were going to feel cheap and flimsy but I was wrong. They feel sturdy and well built (within reason as they are simple blocks with magnets). The kids had fun with them and they feel like they'll last a while. The only reason I didn't give 5 stars is I think they could of added a couple more blocks for the money. I think it's 19 pcs. With one kid it would be suffice but sharing between 2 doesn't work. It still is a great buy though. If you're looking for something like this you won't be mad at your decision.

Wish they were denser
A couple didn't hold up to my daughter's chewing As I was unpacking these, reading the instructions, and not paying attention. I wish the material was denser. They have an almost suede feel to the outside and my 1-1/2 year old daughter was very interested in them as my husband and I were making things, too. But unfortunately we have to be VERY attentive when she plays with them to keep from biting chunks out.

Not A STEM Toy For Kids Over Age Four!
This is really a toddler/pre-school toy--and an expensive one. My first three photos show what you get in the 100-piece set. Only the 12 round and square pieces in the first photo have magnets on all four sides of the block, and those are the only ones that could really stack into a tower. The ones in the second photo have two magnets per block, so they only really construct small objects like the robot or airplane, etc. The blocks in the third photo have only one magnet per block, so they are really limited to decorating a block structure. The video for the 100-block set is very misleading. The "tugboat" can't be built with the 100-piece set because it requires ten of the 4-sided square blocks but the set only comes with six of them. The "vehicle" cannot be built with the 100-piece set because no wheels come with the set. And the huge tower would require 200 of the square blocks alone --but the 100-piece set comes with only six of them. And that doesn't take into account all the accessory blocks that it took to build that structure. It would take almost 1,000 blocks to build it!! So this is not a fabulous, creative building set in any way--very disappointing and very expensive! Does anyone really want to pay $139 to build a robot or have some bath toys?! I am returning this set.

Love them, just a little pricey
These are such cute blocks!! A little pricey, but they are good quality. The magnets in them made me a little nervous, but they really seem like they cannot come out. My little one LOVES playing with these in the bath and the fact that they stick to the sides and bottom of the tub make them even more fun for her.

Surprisingly VERY COOL
We received these on our STEM subscription, and honestly, I did not think much of them. However, our children cannot stop playing and creating with them! Took them away from the screens and they became engrossed with Blockaroos for DAYS! We have added a bunch of sets to our wish list for birthdays. Very well made, very ingenious designs, and the end users are very happy with the results. Thank you!

Startup set, weak magnets
Nice startup set. You dont get many, but if it's for a lil one it's awesome for building and bathtime. As stated when the kid goes to pickup and travel with it, it falls apart. Weak magnets.

Good product, terrible packaging
Fun toys, easy to play with for a 2 years old or even younger. Few things I don't like: The packaging, they re just thrown in a big box without protection or not even little bags, so all the toys came scratched and dented since it's just foam. The box is way too big, the toys can fit in a box 4 times smaller. Last, I think it's a little overpriced.

Moldy Magnets?
My daughter LOVES these toys and uses them in and out of the tub and they would definitely get a 5 star review from her. She loves how they attach to each other and can rotate against each other-endless fun! Unfortunately, the construction of these toys do not bid well to being used as a bath-time toy like they are advertised because they are a nightmare to clean if I wish to get all fo the water out each time because the magnetic part of them is a concave reservoir with a rotating metal ball within. Needless to say, there are plenty of places for water to hide and consequently, mold is prone to grow within them. The instructions do say that they can be put in the dishwasher which is a great feature but its just not practical to out all the pieces in the dishwasher each time. We will be keeping them but its annoying having to encourage my toddler not to take them to the bath each time.
