Purchased the worlds smallest drone online from Storsch. Took 4 months to arrive. Inquired several times, response was sorry we have a backload and will be shipped soon. Received with parts missing, sent email asking for parts, received another drone with all parts. Neither one work as per directions included. Also ordered sd card, it was not required, no mention of this in the add. Again an attempt was made to correct this, still no response.
