MOBIUS Toys Stem Kit Educational Toy and Kids Engineering Kit, 165 Piece IQ Building Blocks Creative Science, Best Non-Toxic Learning Builder Set for Boys and Girls Ages 5 6 7 8 9 10 11 12 Kids Gift

I bought this toy for my 5yr old. Something different from the common Lego blocks. Just received it today (12.23.2019). While helping my son build things I noticed 1 ball joint is slightly bent-in like it was stepped on, then later on my son pointed out 1 of the yellow connector is damaged, like it was melted during manufacturing, it does not look like it snapped during packaging. Anyway, could have been a perfect gift, besides those 2 parts defective out of the box, it's a good, fun/challenging toy.I think it's more suited for 7-10yr old. The red (smallest) connector is very hard for a 5yr old to pull out off the ball joint once connected.The toy itself deserves 5 stars, the plastic part are sturdy, also 5 stars, price point is fair but quality control is horrible on this batch. I don't have any experience buying legos that have dented & melted pieces - so yup, it's a bummer, 3 stars it is for receiving a defective product!

Overall this children's toy it was a great gift for my five year old. The one drawback I saw about the toy was the difficulty in snapping the pieces together. As this was easy for me and difficult for my son, find it difficult to play with it by himself but it is a great opportunity to spend quality time with the kid doing an activity that I enjoy also, building.

Just got it and can’t stp playing with it.The kids love that game playing for 2hours already.That means quiet time for me.Thank you

These were incredibly poorly made and super small. Not at all what I was expecting. I'm glad they were for my classroom and not a gift.

It’s a great building toy for all ages. My 5,7&9 year old really enjoy it. So greatly appreciate that it comes with a storage box as well!

My son gave up playing with his super hero toys to use his mind and creativity.

I didn’t actually use this product as we donated it to Tots for Toys for Christmas. I thought it looked like a child would play with these for a long time.

Both our 2 year-old and our 4 year-old love this building kit! It encourages creativity, and has provided hours of fun.
