Most played toy in my house (ages 2-6)
I’m just coming on here to say that we bought the largest set of these 2.5 years ago for my then 4 and 2 year olds. My son in particular enjoys playing with all types of magnetic building equipment so we practically own a set of all the ones out there (magnatiles, clixxo blocks, magnetic 1 inch cubes, etc.). Eventhough he is 6 now he still comes back to blockaroo EVERY DAY to build creatures, animals, monsters, spaceships, etc. my daughter also gets creative with them and includes them in her imaginative play. I’m continuously impressed by how well they hold up in the water and on land and how much play they have encouraged over the years. I’ve got no complaints at all. I just wish they came out with more shapes and more large sets. They have really been worth it for us.

Fun creative blocks
We love our blockaroo’s! They’re just very expensive. We’d buy more if they were more reasonably priced. I don’t recommend for too young of kids bite marks or being too rough will leave lasting marks.

Almost perfect....
I love these, they are super well made, fun, and encourage creativity. My two toddler grandkids love them. I took off a star because the storage container is SO perfect, but, it is not usable as a storage container. The blocks only fit into the trunk for shipping, placed perfectly aligned. If the manufacturer made the trunk just a bit larger, it would provide really great storage. Such a miss for a pricey product. I have to purchase something to store the blocks in now. :/

Expensive and you need lots of them but worth it
Really expensive, and you should really spring for the large set. We have this set plus a large set in the car. It was really expensive, but this toy is played with daily and we bought it when our kid was six. Our six-year-old plays with a daily and when we have kids over, they all love playing with it. We bought it after playing with it at a friend’s house after the mother told me that this toy had survived dozens of toy purges throughout the years as it was so consistently played with. It’s expensive, but it seems to stand the test of time in terms of interest from kids. It’s also lightweight so they can move a giant box of these around ( they are probably moving $200 worth of blocks at that point but 🫠

Great toy - teeth marks visible if bit
This is a wonderful, open ended, toy. The magnetic strength is both strong enough to feel sturdy and easy enough for my 16 month old to take the blocks apart. My only warning is that there will be teeth marks if your kid decides to bite down on the blocks. The material is foam so the teeth marks do not disappear.

Great Product !
Two and four year old grandsons love it. They can spend hours playing with it, making different creations. Very durable and easily cleaned ! Also extremelly sturdy. Have some other sets of Blockaroo that have been used for to years and the are as good as new.

Super fun but not as versatile as magna tiles
We are big fans of magna tiles and building in general in our house so I bought these to add to our block collection. They are really fun and satisfying - we are yet to use them in the bath. Because of the price, I’m careful to pack them away and out of sight when we’re not using them. (I get them out as a treat to play with for my 3 year old when the 1 year old is napping). Because of the foam that they are made from, the 1 year old would definitely ruin them because he would bite them to bits. So keep that in mind. They are a fun addition to our toy collection but we probably won’t use them as regularly as magna tiles or duplo etc.

Great educational toy for creative play
My kids absolutely love these magnetic foam blocks! They are lightweight, safe, and very easy for little hands to connect. The quality is excellent, and they encourage creativity, problem-solving, and STEM learning while keeping children entertained for hours. The colors are bright, and the pieces are durable enough for everyday play. I highly recommend this set for families with young children.
