I use the clover iron to fuse iron on pieces for machine embroidery appliqué. After the machine makes the outline stitches, I fuse the fabric into place and then continue with the rest of the machine embroidery. With the clover iron, I can get into the small space of the hoop and don't really have to move away from my machine. But I agree, it's not very hot ( except if you get it against your skin!) and don't really use it to fuse something REALLY well - just enough to stay in place to finish an appliqué.
