The center connector was a great concept and so easy to set up. However, by the 3rd time I used it, we couldn’t release the center knob. We had to unscrew the mechanism to fold it. best Choice Products were very customer oriented and immediately sent us a new one. But, the same exact issue happened - by the 3rd usage, it wouldn’t release. The company is honorable and refunded our money and were very eager to please. However This canopy’s design is flawed.
