For what you get, the Sunny 14-inch threaded dumbbell bars are a deal. They take standard plates, and the spin locks have a round bit of rubber to help keep the plates on the bar where you want them. That said, I did experience some loosening of the spin locks as I did my sets. Slight inconvenience, but a minor issue that is acceptable when you take into consideration the price of the item, at least for me.
