Great for other uses

I do not have a DJI Phantom, but I have 2 other drones. I tested this set on it and they worked fine. But, what I purchased it for was other electronics, specifically in my line of work, information technology. I work on wireless access points, cell phones, laptops, switches, servers. Tiny screws that are difficult to hold on to. Having a magnetized screwdriver is priceless. I've dropped so many proprietary screws and spent valuable time trying to find them. This is a decent set with a variety of ends. It's simple to change out the tips and they are held securely. It isn't the most durable, but I need it more for precision than I do strength. The case is a little flimsy, the tips don't always stay in place when it's open. But, the size makes it very convenient and when it's closed, everything does stay in place well.
