Covert drones sourced the M4T when other suppliers could not. Drone and accessories arrived in new condition, and was very responsive when I had difficulties with shipping.
Charger arrived quickly, works great and charged three batteries plus the controller with WB37 very fast. It did get a bit warm but that is to be expected. It's cool being able to see the voltage going to each battery and the charge level. I'd say this is an absolutely essential accessory for the Matrice 4T
This drone is great for many reasons, but the real stand out for us in Search and Rescues is the AI feature. It will always see people before we can see them. Then, with the incredible zoom, you can zoom in to confirm. Covert Drones were also great to work with.
