Brooke,
I am so glad that you got the larger size. I have the mini one and let me tell you that one of the first times i took my little one out she pulled it right out of my hand and was running along the sidewalk and it was dragging along behind her. It actually slowed her down thankfully as she was heading for the crosswalk in the street. Needless to say I went one size up (as you did) and now my hand fits in it properly and I always have a good grip on my little one.
I do use it when I am training her, I will it extend it out a little so the handle drags and do the sit and stay with her, if she starts to walk away the handle drags behind her and she stops. I love my flexi leash. I do agree that it does not work well for training them to heel properly.
