Beautiful Quality Blocks!
Holy moly these are great! Hands down best toy Iâve purchased. These are the perfect weigh and size for my four year old, heavy enough to satisfy his need to lug things around and light enough that they wonât hurt him when his structures fall. The fact that theyâre hollow is genius, these have been parking garages, forts, helicopter landing pads, the North Pole, and âour new houseâ and weâve only had them for 30 minutes. I was concerned that 18 wouldnât be enough to build with but there are plenty or blocks for him to use. Great open ended play and fosters so much creativity!They are smooth and the coloring is beautiful. All corners are rounded and the fasteners are inset. I can tell these will last for years and years. So happy I found these!

Stellar block set!
Silly expensive, however, these are one of the best toys you can get your kids if you can afford the splurge. My girls (1 & 3) have used these at least once, usually several times, a day since we have purchased them. So far, they prefer to use these for games where they arrange the blocks in various configurations on the floor and walk on them. Blocks are sturdy and holding up great to lots of rough play. I’m confident they will last a super long time and make a great hand me down gift for a friend once our girls have outgrown them. And such open ended play options! Love these blocks and the creativity they are inspiring!

These are great!
Iâm so happy! I knew my son would like these because they are hollow. I saw another set like this on another site that were $400. I couldnât do it, lol. So glad I found these. They are solid and VERY strong. My son immediately started building without me showing him and even made a path that he walks on with them. They hold his with no problem. The end of his path turns into a ramp for his ambulance. I highly recommend these.

Very cool!
These blocks are great! I was hesitant to buy them because the price for only 18 blocks seems to be a bit excessive but I decided to go for it because of other reviews. My little guy is going through a phase where he likes to manipulate large objects and test his strength. These blocks give him an outlet for that need, giving him something appropriate to lug around and they are fun to build with! Eighteen doesn’t seem like many but it really is enough once you see them in person. There is a nice variety of blocks, giving options. The two flat boards are a little out of place with the other shapes, almost like they were scraps or just filler. Perhaps we will find more use for those as time goes on.I am most impressed by how responsive ecr4kids customer support is. I contacted them with a question/concern and my message was replied to in a timely and professional manner. I have several products for ecr4kids and have no complaints! Highly recommended!

Package used and defective
Very disappointed. I ordered a new set of these blocks in November 2024 and only received them February 2025. The blocks arrived all bunched up together in a Target box. To add injury to insult, the blocks were clearly used and defective. Not worth it.

Great Modular Blocks, Lots of Possibilities!
Fantastic modular play set. Great for my two boys, ages 3 and 6 to play with together. We’ve had it for 3 days and have already created ramps and obstacles for monster trucks, wooden train tracks and magic tracks. It’s also great as a little platform for playing with Lego vehicle creations. I was skeptical at first, but now very happy to have purchased!

VERY Heavy for over 3yr old (sturdy & many uses)
These are big and sturdy. Kids can stand on them. Not recommended for kids under 3 as they are also VERY heavy. Kids that like to knock blocks over will get a hurt foot. I bought these for my 2 year-old grandsons birthday and we had to keep them in the box until he was just over 3yrs. (because he would knock them over and hurt his feet) other than that⦠These will last a lifetime and then some I would guess. Weâve use the big ones for steppingstones⦠And add the flat long one across so it becomes many balancing beams. There are many uses for these.
