I bought this after the 30 inch broke. The product image for both has the same drone occupying the same space in both pads, but this pad is only about 21" in diameter. The dimensions are not listed in the description but are in the fine print on the third product image: 55cm. I missed it. Basically you have almost no margin for error. The posts when extended reach the edge of the landing which means you have to dead land with Air 2 (which is small) every time. When I land on the Beach, gravel or tall grass, I need room to bug, I don't want to create rotor wash on landing (or take off), throw up particles and destroy my drone.
