VIFLY Finder Mini - Micro FPV Drone Buzzer

Arrived four days ago, not been out to try them bad weather

IMO the best Buzzer for small and medium-sized drones.
The support department answers questions quickly and is very helpful.

I like that so much and I bought 3 more that. plug and play or be fixed. and very useful

Good quality

I ordered 3 units and they came with wires to plug into the drone power system.
DJI has nowhere to plug these devices into.
I may have made a mistake during the ordering process. I say this because I already have an older Vifly unit for another drone that is self powered and is charged using a USB connection.
I love the ViFly product because if the drone comes down which can hapen due to many uncontrolable reasons, the drone can always be found if equipped with the ViFly device.
I have contacted Vifly a little over a week ago and am waiting for instructions to see if I can return these and get them exchanged for the wireless self charging units if they are still available.
attached pictures are of old unit attached to drone and the newly received unit.
