The upgraded structure is reported to provide decent stability, although some customers have noted that in very windy conditions, additional anchoring might be necessary. The PE cover is UV-resistant, offering protection from the sun's harmful rays, but it's not completely opaque, which could lead to heat build-up on particularly sunny days.
