Review on STEM Kit For Boys Ages 8-12, DC Motor Model Car Building Set, Electric Engineering Science Experiment Projects Gift For Kids 8 9 10 11 12 by Jonathan Ulsth

We were looking forward to building this with our kids based on all the positive reviews, but we had the following issues already after attempting to build just two of these:1) The plastic tray for bubble machine cracked on the side so it leaked and we can't use it to fill the machine2) One of the long wheel rods was missing, so we had to take for another kit set.which means eventually one of the kits will not have enough parts3) Some of the kits screws and brackets were either too large or too small for the intended purpose so we had to try our own parts or modify the pieces for assembly.Good concept, needs better execution.
