Pros: Love the feel of it. Without the bungee you can feel your restriction in the movement. This really matters when your trying to maintain muscle memory. You keep consistency. Love the bottom rubberish material. Sits well on my desk and doesn't move.

Cons: None really right now. Love it so far. Only fear would be possibly the rubbish coating on the bottom might wear out over time. But the price is great ill just buy a new one if that is the case.
