Advexure's staff are amazing to work with. We placed our order and it was shipped ahead of schedule! The training for these drones and accessories is also top-notch. The sales staff and office staff are extremely knowledgeable, especially in the realm of public safety! Their outside salesman for our area is an experienced drone operator with numerous hours of public safety flights. So, he can share with us what works and what doesn't in the field. They listen to what your needs are and tailor your needs with the appropriate equipment. Not only that, they also train you on how to deploy this equipment efficiently and effectively, so that you are not scrambling during an emergency! I highly recommend Advexure for your drone and mapping needs!
