I have the JoAnn one and am not completely happy with it. I'm waiting until I get my swift to see if it behaves better. But I wound a couple of balls of yarn that I had already wound by hand from hanks into balls using the JoAnn swift. The arm the yarn guide is on doesn't lock in position no matter how far out I pull it and after a while it falls over and you have to put it back up or catch it as it's leaning. I ordered my swift a week ago so when i get it, if the ball winder arm somehow doesn't fall down in conjunction with it, i'll post again and let you know.
