Universally Drone Airdrop System Release Device Payload Delivery Transport Drop, for DJI Mini4/Mini3/Mini2/Air3/Air2/Air2S/ Mavic Series Drone Accessories (Mechanical Claw)

I just unpacked the claw and tried to operate it. Blue light flashing on claw, but Remote does not work, even with a different brand new 9 V battery. Smacks of poor quality control. Low confidence in manufacturer’s competence. Instructions are (politely described) “minimalist”. Cheesy packaging suggests cheesy manufacturing process. I am returning product promptly.I also noticed that all the other vendors on Amazon have exactly same remote and claw design.

Range for the remote control is excellent. I have used it over the length of a football field if there are little obstacles. It can carry things like eggs or nerf balls and drop them on command. Pretty cool for the money. Used with DJI phantom and Mini 3.

I like how you basically your strap it and it has a really long band so it’ll fit basically any type of drone and then it’s a simple hook and release so it’s reliable

Used to remotely trip a feral cat trap, which it works great with. The battery holds up well, lasting the day. We recharge every night. FYI, the trap is a kennel, with a small access. This remote holds up a wire panel that will cover the access when released.

Range is awesome, tested successfully at ~1 km in rural uninhabitant area.

A lot of fun. Be careful if drone has obstacle avoidance not to interfere with it

This gadget, which I am calling a grappling hook, but which the manufacturer calls an airdrop system is, indeed, much more suited for dropping than for grappling. I bought it in hopes of being able to grab and remove bird's nests from the roof of my two-story house, too high for me to get up onto. I have a DJI Mini 4K drone, one of the drones the device is supposed to be compatible with. It works more or less, but the DJI Mini 4K, which alone is extremely stable, becomes rather unstable with the grappling hook attached. It will sometimes climb, and sometimes descend, and sometimes move horizontally even when I am not touching the control sticks. I speculate that this is because the hook attaches to the drone with a strap around its middle which may throw it out of trim, and that the hook itself may confuse the drone's camera-based stabilization system.After several tries I had to give up trying to grab the nest with the hook. The best I could do was drop an old shoe on the nest in hopes that the birds will abandon the nest and go elsewhere. In fairness, they do call it an airdrop system and not a grappling hook. Still, lack of stability is an issue.The device basically works as advertised, but loses one star for making the drone unstable and therefore much harder to control. The grappling hook has a built-in rechargeable battery, but the remote uses a regular 9-volt battery. The remote also has confusing switches: The on-off switch has meaningless labels. (Up is On and Down is Off) and the controls for the hook say "ON" and "OFF" rather than "Open" and "Close" and this is also confusing. I've subtracted one star for the overall poor design of the remote.Overall I rate it acceptable. Three stars. It might work better with a bigger, more powerful drone.

​I recently purchased this airdrop system for my DJI Mini 4 Pro, specifically to help with hanging Christmas lights on high trees around my property. I am honestly impressed with how well it performed.​The installation was straightforward and didn't interfere with the drone's sensors or flight stability. It fits the Mini 4 Pro perfectly. For my specific use case, it was a game-changer. Instead of risking a ladder on uneven ground, I was able to lift the strands of lights and release them exactly where I needed them on the branches. The release mechanism is responsive and reliable.​Pros:​Precision: Allows for accurate placement of items (in my case, light strands).​Fit: Snaps onto the Mini 4 Pro securely without adding too much weight.​Ease of Use: Simple to operate; the trigger mechanism worked every time.​If you are looking for a creative way to decorate for the holidays or just need a reliable payload release for your Mini 4 Pro, I highly recommend this system. It turned a dangerous, all-day chore into a fun and quick task!
