Well, the zippers work. And the tent material is thicker, more pliant.
Most cheaper tents have super thin nylon weave, the Apollo tent has more rugged material including
for the flaps for the zippers, the material doesn't fray and get caught in the zippers which work flawlessly.
If the manufacturer has a long explanation on their zippers, they aren't YKK zippers and suck.
The holes for cords have a better layout for me, you should look carefully at the duct/ cord cutouts or lack of them before buying.
