18 Set DC Motors Kit, Mini Electric Hobby Motor 3V -12V 25000 RPM Strong Magnetic with Shaft Propeller, 2 x AA Battery Holder,9V Battery Clip Connector,Plastic Wheels for DIY Science Projects

This is a good complete kit. There's plenty of everything and it all works. The plastic pieces are strong. The wires are really thin, but good enough. The motors work well. The directions are next to useless, but you can find whatever you need to know online. Within 30 minutes, my 13 year-old had a working car with two drive wheels and a propeller. It really scooted across the floor! He used craft sticks and a hot glue gun to create the frame and hold the electrical parts in place. You also should probably have a soldering gun to secure the connections.

The techie students in my class had a blast with these. 4 students created a museum for our simulated city project and had the “gift shop” just outside it. They made cars, fans, and other nifty creations with this kit. Very fun.

I'm 10. I love this set. I've made several projects.

Excellent for classes and projects. The nodes on the motors can be damaged of you aren’t careful but you can tape the wired parts after.

Used these at a STEM CLUB event at my school it was great for all the accessories and learning!

I had purchased a smaller (6 motors, etc.) , 3-volt version of this. It’s great. I ordered this for the higher-voltage motors. I mean come on, the price makes it worth the motors alone, and these switches… and everything else.

Excellent and perfect productMy 11-year-old son really enjoyed the gift he received, employment for hoursThank you

The connections on these motors are sooooooo bad. They break very easily - soldered or not.Also not that great for kids. Not easy to use. I ended up getting Snap Circuits and we are much happier with them.
