The material is strong. Don't really have any data on durability and sturdiness yet. For those who have never bought the more rubbery ones, is they sound like a * gun shout when you slam them on the ground.

This med ball is a great value ($32! I train clients out of my garage gym and they like them. Makes for a great workout. Well worth the price.

Medballs should be thrown and slammed for years with no issues. It feels like a huge, over inflated volleyball. As long as you don't use this to bounce against the floor or wall, it's fine.

This ball is an obvious knock off of the dynamax ball, but is a much cheaper chinese-made version. This product is not turquoise. I wouldn't recommend this product to anyone who is looking for a durable, well-made piece of equipment.

This 6lb seems defective, maybe hollow or unfilled. It was unequally weighted again and significantly flattened on two sides. This item was shipped with no nuts and bolts to assemble.

The exterior is a slick synthetic leather with poor tactile design. They are like a slick pleather material.
