The fruits are certainly edible, but there's not really anything that wonderful about them, and they have little edible flesh, and some small seeds that you kind of have to chew around.
The flavor, to me, is like a mix of mango, strawberry, and apricot, and they have more the texture/consistency of partially cooked pumpkin, maybe a little bit of the texture of a mango, medium in ripeness. They are not really the strongest in flavor, and are maybe just a little bit bland.
Usually the trees are not considered worth it for their fruit alone, but are desirable for a combination of ornamental small tree and partial edibility.
You might only want to eat only a few (1-4) of the fruits and will not feel like snacking on any more at a time. It does take some work to nibble small bites around the inner part that contains the seeds, since the fruits are already small.
The flesh of the fruits is just a tiny bit grainy, as well.
