I did, and the small (orange and blue) is too small. I can't get my fat arms close enough at address for it to hold the ball. I've tried the large (yellow and blue) too and it's too big--rests on my fat belly moreso than in my arms. I'd go with a medium (green and blue color). And it can really help with putting/chipping/pitch shots. Full shots I can't comment on until I get the right size ball myself.
Try using the small one for putting. It helped me get the feeling down on my putting. And the small isn't large enough for swinging.
