STEM Kits, Kids Arts and Crafts for Girls 8-12 8-10, stem Toys for Ages 8-13, Engineering Science Kits for Kids, STEAM Gifts for 6 7 8 9 10 12 Year Old Girls, Electronic Building Boys 6-8

These were purchased as a gift for my grandkids in Florida. I buy everything for them on Amazon, because they're so far away from me. They absolutely loved them. I got two sets for my son's girlfriend's kids, and for my grandkids. And they all had a great time. Very good quality, and they seem to be lasting. Age appropriate as to what's listed. The kids ranged in age from 7 years old to 11 years old, and all of them enjoyed putting these together and playing with them.

My grandson loves these kits. He’s learning essential skills while having fun. They are sturdy with all parts, tools and instructions included. We home school and this is a wonderful supplement to the curriculum.

My 6 year old loves to fix stuff this was honestly a super cool kit! I thought it was going to be alot bigger but for size reference the screws are as big as eyeglass screws. The instructions are clear.

It's a good learning diy. Requires adult supervision. The only concern is it's small in size and the packing could be better.

Great for my 6 year old to take a challenge

Gave these to my nephews as a Christmas gift and they were HUGE hit!!!! They actually said they hoped we would do that again for birthdays and Christmas!

Great birthday gift for enquiring minds

First step: just a picture, no horizontal or vertical placement direction. Two different screw sizes with no instruction on which one to use.

Big hit with grandsons. Both love it. Going to buy them more kits like this.

Instructions were not as clear as other step by step building toys. The screws didn’t fit smoothly, was too difficult for my 8yr old she couldn’t make sense of the instructions. I took over building the going chairs and the end result was underwhelming. The chairs kept hitting the wire that powered the device and disconnecting so would spin for 3 seconds at a time. Way too much frustration to get to an end product that was underwhelming and didn’t hit the mark.
