I was really excited to to try the Titan Fitness Youth 3-In-1 Heavy Foam Plyo Box – 12" x 14" x 16". We received it quickly and we got it right out of the box and started to use it for my 8 and 10 year old hockey and lacrosse players. After only 8 days of both kids working out with the Plyo box under my supervision (so I know it wasn't mishandled), the outside vinyl cover started to tear open. Sad that the product is not more sturdy and reliable than it is. An 8 year old and a 10 year old, doing 1 workout per day on this should not cause this product that much damage. I am extremely disappointed with the durability of this product considering it costs A LOT of money for something used for youth athletes.
