The fruits are 1 1/2 to 2in across, and very seedy, but tasty. The trees bear heavily, although some of them are heavy/light bearers, one year they will have a lot of fruit and the next a light crop. They are really pretty, small trees, don't know if they're thorny or not, that seems to vary with the variety. My Key Lime has no thorns at all but I have a friend who has one that is very thorny. She just clips off the thorns she can reach, and that works for her. My Kumquat has no thorns either.
