I committed to do 80 Day Obsession by Beachbody buy my order was delayed three weeks. You need these immediately, so I ordered them and prayed they didn't suck. They didn't suck. They're actually better than the BB ones, IMO. They slide perfectly in my carpet and hardwood floors (I workout in my living room or family room.) Your feet (in shoes) don't slide off the disks. I am pleased and would buy again.
(PS I'm a plus sized gal, my weight did not impede them from sliding which I wondered about. So, my fluffy gals, this product IS for you too!)
