I used these for a homeschool field trip and definitely a worthwhile purchase. Great stuff

Comes with everything you need to put a little something together

Only giving this 4 stars because I think the instructions could be a little better. My son and I had fun playing with this and soldering up the motors and batteries. Melted a few battery cases because the instructions were tiny and hard to read for us, but we are almost blind. Also the motor had a hard time spinning when one of the provided rubber bands was on the main gear, they need a little more torque.

Well when I ordered it for my daughter her birthday is coming up and she sees me always working on things and doing electrical jobs or just building motors and what not and she always wants to help so I decided to get her her own little kit and The package arrived extremely nice I mean this thing was great looking I wish I still had a picture of it I should've taken one actually I did but unfortunately I've been very busy and I didn't get a chance to do the review right away anyways I cleared out my phone and it's gone but I did find this one that is listed I mean these things were perfectly package they were all super sealed in their own individual bags were all the components were in there the motors were by themselves in their own little bag and vice versa So that stuff was great!

HOWEVER"¦ when I got to the motors and I opened my package I was very confused because all of my motors were very clean and they looked brand new and then I noticed the bag had a collar on it right where one motor was sitting I thought it might've been dirty so I looked closer and I take it out and realized the motor is actually rusted and I mean that a little bit this thing was rusted where it was stained on the bag itself and that confuses me a little bit because there was no holes in there and if none of the other motors were doing the same thing that means this motor had to have been placed in there probably out of another batch that maybe had a bunch of them rusted? And maybe it was done just to divide them up and get rid of a few by sending them in a few packages rather than just tossing a whole set out? I have no idea it's the only thing I can really think of that makes sense because these things were sealed very tight and Ziploc bags there was no holes in it I even put some air in it and pushed on it so I was very confused it seems like whoever had put it in the bag obviously knew it was rusting at that time dropped it in and it just kind of took off from there but other than that"¦

I would say this was a nice little kit because it has a variety of different things and they're great for kids she was very excited of course I did not let her see the motor that was rusted as it was a birthday gift and I didn't want her thinking any bad thoughts so I made with what I had and she just got shorted a little bit but I will say the packaging was done very well and I guess that was the only thing that threw me off a little bit because I saw how clean it was and I didn't understand how it could've gotten to that point unless it was literally put in from another bag that maybe had caught a hole or sat too long or both. Either way it's a fun little set and the shipper did have it arrive quickly I appreciate that now I don't give them any bad stars for the purpose of not replacing or anything like that because honestly I'm just now getting a chance to do this review and this is back from around April 10 roughly so I have not reached out to ask for any type of replacement or anything but that would be the only thing that would be on the downside was the one motor everything else and all the other packages were great and sealed awesome she loves it I think I would consider purchasing again as I do understand once in a while things do happen it was just a little confusing was all for how sealed everything was but thank you again I do recommend I think I just got a little bit of a bad package on that one but besides that they are super clean well-built great for kids to learn with and she loves it and you can also transition and kind of join them together with your Legos with some hot glue and what not that's what we did I do recommend that thanks everyone

Nice set for beginners
