Decent quality product for the price. Would be great for beginners if they were a bit more sturdy. Can be hit or miss with the product that gets shipped to you. Had a little over 10 of them for students to used during a moon landing competition this summer and had some issues with one having a faulty servo straight out of the box. Didn't work and was not usable. Another had a cut yellow wire sticking out of one of the quadcopter arms right out of the box. Others lasted a handful of flights before becoming non-functional. 6 seemed to last pretty well throughout students using and at times abusing them while learning and crashing. Having taken one apart, the wiring is pretty delicate, so definitely plan to purchase extras if you're planning to use these for teaching students how to operate drones.
