Sntieecr 6 Set 131 PCS DC Motors Kit, Science Experiment Kit Mini Electric Motor 1.5-3V 15000RPM with 66 PCS Bulbs, Buzzer Sounder, Shaft Propeller, Instruction, for Kid DIY STEM Engineering Project

I bought this for my 8year son old is so interested in Engineering and he loved. The package arrived next day he made couple of things from it. It was easy for him to understand. Good value and fun. Surely recommend

My 8 Yr old daughter and her uncle who is 10 love playing with these! They really like it and get very excited when they play with it + its educational allowing a fun learning experience while playing

While the concept is excellent and has brought my son hours of fun, the quality of everything is very, very poor. Several propellers have broken as they are far too flimsy and the battery pack wires are too thin and weak. The ends of one has already fuzzed up and is no use - I'll try and use my wire stripper on it. The spare cable is also of the lowest possible quality. Not sure what all the cogs are for - just to increase the number of parts in the set??? Very sad - please increase the quality of the product and reduce your profit just a little, it will surely pay of with more a d happier customers.

Its a bit pricey for what it is, none of the crocadile clips hold the wires so its more of a electronic componant assortment then a kit all usable but not as plug and play solder is needed or a bread board, plus we added all the bits seperatly and it was much cheaper to buy all of the componants seperatly, you got more for your money and enough for solder and a bread board not buying this box of bits

Really good kit for my teenage son to use. Could have came with a better instruction manual. I don’t know what some of the bits are for as the guide that came with it was just a few pictures.
