I was looking for something small to improve my skill and my fingers especially muscle (PCQ the thumb will ca .. but the others), I chose to start with this model because I'm a girl and I have not much strength and I did well! It's not too hard but enough to keep using it! (I have a little trouble with the little finger and ring finger! But it's going to get better!) In short, a nice object, perfect for use as I have. It looks solid and it is small enough to take anywhere, to look perfect in the subway!
