Whoever came up with the idea for magnetic blocks is a genius
My grandsons love these! Whenever they come over they go right for these blocks. I ordered two more sets for a total of 36 so they can both play with them.

Great toy in and out of the bathtub
My grandchildren love Blockeroos. This is the 3rd or 4th set I have bought. They are expensive but they last and continue to be enjoyed in and out of the bathtub. Perfect for 2 yrs and beyond. If they want to bite them wait until that phase has passed since that can ruin them.

Nice gift for toddler
Nice blocks. Got this as a gift for my 3-4 year old nephew & he enjoys them. He’s able to play with them on his own & build random things.

Almost perfect
Lost a star because they're not the same size as the other block-a-Roos but The kids love anyway. Great toy for any age. Strong enough to make some pretty cool things but fall apart when stopped. Brite and fun colors

Fun and creative toy
My 2 year old and 5 year old love this magnetic toy. The magnets are strong and work well unlike some other magnetic toys. While my 5 year old uses her imagination to create all sorts of cool things, my two year simple enjoys putting the magnets together and taking them apart. He also loves the ratcheting sound the magnets make when you spin them. Great buy for a variety of ages!!! Definitely plan on expanding our collection.

Magnets were lose on all blocks upon arrival- updated
So silly me, I didn’t read the booklet until today, because what do you really need to know about foam blocks? Well, it says to inspect to make sure the magnets are lose. All of mine were. They make rattle sound. Which I thought was normal. I’m not thrilled because these were 80$ for something unsafe. Who can I speak to about this? Update: I did reach out and customer service said this was normal for the product. We’ve had them almost a year now with no issues. Easy to wash and my littles still enjoy them!

These are fun even for adults!
I bought these for my grand daughter for Christmas. When I am at her house, this is one item we usually play with every time. Because they are magnetic, she enjoys taking them and sticking them to a metal file cabinet they have in their living room. There are all kinds of shapes and sizes so we will make dumb bells out of them, castles, ice cream cones, even balls to bowl with. We take some of her other small toys and put them up like bowling pins, and take the half round shapes and put together and use them to bowl with. It's so much fun. This toy has endless possibilities. I totally enjoy building with her with this set. Hope this helps.

Brilliant fun, hours of play
Our 2 year old is having a great time with these. Although I think the price is a little steep for the amount of pieces you get, my little boy is having a great time playing with them. It allows children to really use their imaginations to connect them together and build different things each time. However I will say I feel once you build a little top heavy or try to pick your design up, it doesn't take much to break apart. Not much of a big issue though, they're great fun.

Great blocks
These are great blocks. My younger child (age 2) also likes them, however, he is still biting things and the foam now has teeth marks. Bit annoying as this set was very expensive. I should have expected this and delayed purchase.
