Exactly what we were expecting!
I have the regular pull buoy from Aquatica and it works well for me, being 5'8" at 155lbs. But when my wife, being 5'2" at 109lbs, used it, the buoy was too buoyant for her. She found her entire hips and legs constantly popping out of the water. So instead, I purchased the Jr. Buoy for her and she loves it. The Jr. Buoy has 4 levels of foam, versus the 5 found in the regular version, making it less buoyant and better for her stature.
I was happy with the product.
