This shit has already been nicknamed mopeds, it flies slowly and makes a lot of noise, they learned to shoot it down.
a very primitive copy of American and Israeli drones.
There is good phrase that you shouldn't understimated your enemy. These drones might be slow and very loud, but so far they have done some significant damage. They fly at low altitude and missile defense systems can't detect them. It's possible to shoot it down with Stingers, but I seen video from Odessa where they are trying to shoot it down with machine guns.
