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.

Incredible!
This is the most used toy in our home by my very active and non-toy playing 4 year old. I wish they’d come out with more shapes because I’d buy them all. Endless creativity.

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.

Quality product, engaging and durable. Like the ability to put in dishwasher to clean.

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.

Really cool toy!
Really cool especially if you have a cast iron tub. Some of the magnets are strong enough to stick to the bottom or side of the tub. We love the way they stick together and click when twisted. They're worth it, bath tub toys can be so hit or miss on quality and these are a hit!

Lovely blocks
Gave as a gift to our granddaughter! She loves it.

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.
