Good variety

I've been building Lego sets for nearly 75% of my lifetime. But when I discovered Technic sets years ago, that was such a game-changer. Brick sets were no longer static display pieces, but actual engineering projects that could be built and rebuilt into some pretty epic toys. This set has many of the parts you need to start building RC brick vehicles and any number of awesome machines. And any time you can pick up a whole set like this, versus buying individual parts, you save money. I'm currently working on a RC Baja trophy truck build that I found on YouTube, and thankfully the guy included a full parts list for the build. This set has a lot of the parts I need, along with a lot of extras. So between this and a couple other sets I've picked up, I almost have enough parts for 3 Baja truck builds. It's going to take me a while to finish them, but I'm going to build at least 2. All the pieces I've tested so far have fit great with my other sets from other brands, and they feel really solid and well made. Overall, if you haven't tried powered brick set builds yet, pick up a set like this and a motor set, and just start building things. Even if you don't have a specific goal in mind, it's just super fun and cool. Happy building!

I ordered this set for my 10 year old to add on to their existing brick building sets as they're always pulling bricks from existing builds to enhance other builds. This allows them to enhance both sets without making one set less than operational.These all seem to work well together and compatible with the other brands of brick sets.

This is an excellent replacement set for EV3 building blocks. With a wide variety of regular-sized mechanical parts, including bricks, bushes, technic pins, and gears, it offers everything needed to repair, upgrade, or expand your creations. The quality of the components matches expectations, ensuring compatibility and smooth integration with existing sets. Whether you're a beginner or an experienced builder, this set provides a reliable solution for any project. A must-have for EV3 enthusiasts!

These are great LEGO Technic clones and seem to mix-and-match well. These are great resource packs if you need more quantity and variety in your collection.

My 11 year old loves this set. I know it’s advertised as replacement parts but he has built a variety of different vehicles and “machines” with this alone.He gives it two thumbs up and 5 stars. The pieces are easy to work with, durable and connect with name brand pieces.

The parts are all perfectly compatible with lego technic parts, and everything seems to fit well and hold well when it should. The gears and axles appear to be of the same quality you could expect from major brands, and they arrived packaged in separate baggies to allow for easier sorting of parts, should you be of such mindset. It's a good way to expand your technic parts collection.

Amazing parts for creative play! Great quality first multiple builds. Good value for the money!
