Was unable to identify the company that built (China) the unit. Purchased the quad from USA company paying 36.99 free shipping, upon opening box no Syma identifier anywhere box or drone. Contacted seller about advertising as a Syma product got the run around finally went thru Ebay received full refund. The drone seems to fly ok first time I have operated one so may not be a good judge of its operation, doesn't seem to hold alt with throttle set. Be very careful about what you are buying shows picture of Syma but ships a clone.
