This was a gift for my grandson! He loved it!!

This kit is a life saver, used some parts that were missing from a build I was doing, parts are made strong and fit perfect. Worth every penny spent. Good idea to buy kit to help with a project that has missing pieces.

Serve their job prefectly, i do recommend They even arrive in the same colour wich is rare for these kind of sets, hovewer they fit a little bit too perfectly they are very tight so harder to build or take them apart than normal legos, also some come with a few defects and its annoying to build with those, but if you ignore all that they are really good

Bought these pieces for my children to make their own “dragsters” they were perfect and great quality! Will definitely buy again!!

Awesome

Had the 2 parts I was missing and always good to have spares of what else it came with

My kids didn't even notice a difference between the name brand and these. They are interchangeable and they've made some pretty involved machines.

All pieces seem to be functional and compatible with official Lego, but some of the pieces in the batch that I received were of questionable quality. So if you ever want to build something for a display, I suggest trying some other LEGO knockoffs instead of this one (there are plenty of really good quality knockoffs out there)
